DESCRIPTION
       ip route is used to manipulate entries in the kernel routing tables.

       Route types:

               unicast - the route entry describes real paths to the
               destinations covered by the route prefix.


               unreachable - these destinations are unreachable. Packets are
               discarded and the ICMP message host unreachable is generated.
               The local senders get an EHOSTUNREACH error.


               blackhole - these destinations are unreachable. Packets are
               discarded silently.  The local senders get an EINVAL error.


               prohibit - these destinations are unreachable. Packets are
               discarded and the ICMP message communication administratively
               prohibited is generated. The local senders get an EACCES error.


               local - the destinations are assigned to this host. The packets
               are looped back and delivered locally.


               broadcast - the destinations are broadcast addresses. The packets
               are sent as link broadcasts.


               throw - a special control route used together with policy rules.
               If such a route is selected, lookup in this table is terminated
               pretending that no route was found. Without policy routing it is
               equivalent to the absence of the route in the routing table. The
               packets are dropped and the ICMP message net unreachable is
               generated. The local senders get an ENETUNREACH error.


               nat - a special NAT route. Destinations covered by the prefix are
               considered to be dummy (or external) addresses which require
               translation to real (or internal) ones before forwarding. The
               addresses to translate to are selected with the attribute via.
               Warning: Route NAT is no longer supported in Linux 2.6.


               anycast - not implemented the destinations are anycast addresses
               assigned to this host. They are mainly equivalent to local with
               one difference: such addresses are invalid when used as the
               source address of any packet.


               multicast - a special type used for multicast routing. It is not
               present in normal routing tables.


       Route tables: Linux-2.x can pack routes into several routing tables
       identified by a number in the range from 1 to 2^32-1 or by name from the
       file /etc/iproute2/rt_tables By default all normal routes are inserted
       into the main table (ID 254) and the kernel only uses this table when
       calculating routes.  Values (0, 253, 254, and 255) are reserved for
       built-in use.


       Actually, one other table always exists, which is invisible but even more
       important. It is the local table (ID 255). This table consists of routes
       for local and broadcast addresses. The kernel maintains this table
       automatically and the administrator usually need not modify it or even
       look at it.

       The multiple routing tables enter the game when policy routing is used.


       ip route add
              add new route

       ip route change
              change route

       ip route replace
              change or add new one

              to TYPE PREFIX (default)
                     the destination prefix of the route. If TYPE is omitted, ip
                     assumes type unicast.  Other values of TYPE are listed
                     above.  PREFIX is an IP or IPv6 address optionally followed
                     by a slash and the prefix length. If the length of the
                     prefix is missing, ip assumes a full-length host route.
                     There is also a special PREFIX default - which is
                     equivalent to IP 0/0 or to IPv6 ::/0.


              tos TOS

              dsfield TOS
                     the Type Of Service (TOS) key. This key has no associated
                     mask and the longest match is understood as: First, compare
                     the TOS of the route and of the packet. If they are not
                     equal, then the packet may still match a route with a zero
                     TOS.  TOS is either an 8 bit hexadecimal number or an
                     identifier from /etc/iproute2/rt_dsfield.


              metric NUMBER

              preference NUMBER
                     the preference value of the route.  NUMBER is an arbitrary
                     32bit number, where routes with lower values are preferred.


              table TABLEID
                     the table to add this route to.  TABLEID may be a number or
                     a string from the file /etc/iproute2/rt_tables.  If this
                     parameter is omitted, ip assumes the main table, with the
                     exception of local, broadcast and nat routes, which are put
                     into the local table by default.


              vrf NAME
                     the vrf name to add this route to. Implicitly means the
                     table associated with the VRF.


              dev NAME
                     the output device name.


              via [ FAMILY ] ADDRESS
                     the address of the nexthop router, in the address family
                     FAMILY.  Actually, the sense of this field depends on the
                     route type.  For normal unicast routes it is either the
                     true next hop router or, if it is a direct route installed
                     in BSD compatibility mode, it can be a local address of the
                     interface. For NAT routes it is the first address of the
                     block of translated IP destinations.


              src ADDRESS
                     the source address to prefer when sending to the
                     destinations covered by the route prefix.


              realm REALMID
                     the realm to which this route is assigned.  REALMID may be
                     a number or a string from the file /etc/iproute2/rt_realms.


              mtu MTU

              mtu lock MTU
                     the MTU along the path to the destination. If the modifier
                     lock is not used, the MTU may be updated by the kernel due
                     to Path MTU Discovery. If the modifier lock is used, no
                     path MTU discovery will be tried, all packets will be sent
                     without the DF bit in IPv4 case or fragmented to MTU for
                     IPv6.


              window NUMBER
                     the maximal window for TCP to advertise to these
                     destinations, measured in bytes. It limits maximal data
                     bursts that our TCP peers are allowed to send to us.


              rtt TIME
                     the initial RTT ('Round Trip Time') estimate. If no suffix
                     is specified the units are raw values passed directly to
                     the routing code to maintain compatibility with previous
                     releases.  Otherwise if a suffix of s, sec or secs is used
                     to specify seconds and ms, msec or msecs to specify
                     milliseconds.



              rttvar TIME (Linux 2.3.15+ only)
                     the initial RTT variance estimate. Values are specified as
                     with rtt above.


              rto_min TIME (Linux 2.6.23+ only)
                     the minimum TCP Retransmission TimeOut to use when
                     communicating with this destination. Values are specified
                     as with rtt above.


              ssthresh NUMBER (Linux 2.3.15+ only)
                     an estimate for the initial slow start threshold.


              cwnd NUMBER (Linux 2.3.15+ only)
                     the clamp for congestion window. It is ignored if the lock
                     flag is not used.


              initcwnd NUMBER (Linux 2.5.70+ only)
                     the initial congestion window size for connections to this
                     destination.  Actual window size is this value multiplied
                     by the MSS (``Maximal Segment Size'') for same connection.
                     The default is zero, meaning to use the values specified in
                     RFC2414.


              initrwnd NUMBER (Linux 2.6.33+ only)
                     the initial receive window size for connections to this
                     destination.  Actual window size is this value multiplied
                     by the MSS of the connection.  The default value is zero,
                     meaning to use Slow Start value.


              features FEATURES (Linux3.18+only)
                     Enable or disable per-route features. Only available
                     feature at this time is ecn to enable explicit congestion
                     notification when initiating connections to the given
                     destination network.  When responding to a connection
                     request from the given network, ecn will also be used even
                     if the net.ipv4.tcp_ecn sysctl is set to 0.


              quickack BOOL (Linux 3.11+ only)
                     Enable or disable quick ack for connections to this
                     destination.


              fastopen_no_cookie BOOL (Linux 4.15+ only)
                     Enable TCP Fastopen without a cookie for connections to
                     this destination.


              congctl NAME (Linux 3.20+ only)

              congctl lock NAME (Linux 3.20+ only)
                     Sets a specific TCP congestion control algorithm only for a
                     given destination.  If not specified, Linux keeps the
                     current global default TCP congestion control algorithm, or
                     the one set from the application. If the modifier lock is
                     not used, an application may nevertheless overwrite the
                     suggested congestion control algorithm for that
                     destination. If the modifier lock is used, then an
                     application is not allowed to overwrite the specified
                     congestion control algorithm for that destination, thus it
                     will be enforced/guaranteed to use the proposed algorithm.


              advmss NUMBER (Linux 2.3.15+ only)
                     the MSS ('Maximal Segment Size') to advertise to these
                     destinations when establishing TCP connections. If it is
                     not given, Linux uses a default value calculated from the
                     first hop device MTU.  (If the path to these destination is
                     asymmetric, this guess may be wrong.)


              reordering NUMBER (Linux 2.3.15+ only)
                     Maximal reordering on the path to this destination.  If it
                     is not given, Linux uses the value selected with sysctl
                     variable net/ipv4/tcp_reordering.


              nexthop NEXTHOP
                     the nexthop of a multipath route.  NEXTHOP is a complex
                     value with its own syntax similar to the top level argument
                     lists:

                             via [ FAMILY ] ADDRESS - is the nexthop router.


                             dev NAME - is the output device.


                             weight NUMBER - is a weight for this element of a
                             multipath route reflecting its relative bandwidth
                             or quality.

                     The internal buffer used in iproute2 limits the maximum
                     number of nexthops that may be specified in one go. If only
                     ADDRESS is given, the current buffer size allows for 144
                     IPv6 nexthops and 253 IPv4 ones. For IPv4, this effectively
                     limits the number of nexthops possible per route. With
                     IPv6, further nexthops may be appended to the same route
                     via ip route append command.


              scope SCOPE_VAL
                     the scope of the destinations covered by the route prefix.
                     SCOPE_VAL may be a number or a string from the file
                     /etc/iproute2/rt_scopes.  If this parameter is omitted, ip
                     assumes scope global for all gatewayed unicast routes,
                     scope link for direct unicast and broadcast routes and
                     scope host for local routes.


              protocol RTPROTO
                     the routing protocol identifier of this route.  RTPROTO may
                     be a number or a string from the file
                     /etc/iproute2/rt_protos.  If the routing protocol ID is not
                     given, ip assumes protocol boot (i.e. it assumes the route
                     was added by someone who doesn't understand what they are
                     doing). Several protocol values have a fixed
                     interpretation.  Namely:

                             redirect - the route was installed due to an ICMP
                             redirect.


                             kernel - the route was installed by the kernel
                             during autoconfiguration.


                             boot - the route was installed during the bootup
                             sequence.  If a routing daemon starts, it will
                             purge all of them.


                             static - the route was installed by the
                             administrator to override dynamic routing. Routing
                             daemon will respect them and, probably, even
                             advertise them to its peers.


                             ra - the route was installed by Router Discovery
                             protocol.


                     The rest of the values are not reserved and the
                     administrator is free to assign (or not to assign) protocol
                     tags.


              onlink pretend that the nexthop is directly attached to this link,
                     even if it does not match any interface prefix.


              pref PREF
                     the IPv6 route preference.  PREF is a string specifying the
                     route preference as defined in RFC4191 for Router Discovery
                     messages. Namely:

                             low - the route has a lowest priority


                             medium - the route has a default priority


                             high - the route has a highest priority



              nhid ID
                     use nexthop object with given id as nexthop specification.


              encap ENCAPTYPE ENCAPHDR
                     attach tunnel encapsulation attributes to this route.

                     ENCAPTYPE is a string specifying the supported
                     encapsulation type. Namely:

                             mpls - encapsulation type MPLS

                             ip - IP encapsulation (Geneve, GRE, VXLAN, ...)

                             bpf - Execution of BPF program

                             seg6 - encapsulation type IPv6 Segment Routing

                             seg6local - local SRv6 segment processing

                     ENCAPHDR is a set of encapsulation attributes specific to
                     the ENCAPTYPE.

                               Operation to perform on matching packets. The
                               optional count attribute is used to collect
                               statistics on the processing of actions.  Three
                               counters are implemented: 1) packets correctly
                               processed; 2) bytes correctly processed; 3)
                               packets that cause a processing error (i.e.,
                               missing SID List, wrong SID List, etc). To
                               retrieve the counters related to an action use
                               the -s flag in the show command.  The following
                               actions are currently supported (Linux 4.14+

              expires TIME (Linux 4.4+ only)
                     the route will be deleted after the expires time.  Only
                     support IPv6 at present.


              ttl-propagate { enabled | disabled }
                     Control whether TTL should be propagated from any encap
                     into the un-encapsulated packet, overriding any global
                     configuration. Only supported for MPLS at present.


       ip route delete
              delete route
              ip route del has the same arguments as ip route add, but their
              semantics are a bit different.

              Key values (to, tos, preference and table) select the route to
              delete. If optional attributes are present, ip verifies that they
              coincide with the attributes of the route to delete.  If no route
              with the given key and attributes was found, ip route del fails.


       ip route show
              list routes
              the command displays the contents of the routing tables or the
              route(s) selected by some criteria.


              to SELECTOR (default)
                     only select routes from the given range of destinations.
                     SELECTOR consists of an optional modifier (root, match or
                     exact) and a prefix.  root PREFIX selects routes with
                     prefixes not shorter than PREFIX.  F.e.  root 0/0 selects
                     the entire routing table.  match PREFIX selects routes with
                     prefixes not longer than PREFIX.  F.e.  match 10.0/16
                     selects 10.0/16, 10/8 and 0/0, but it does not select
                     10.1/16 and 10.0.0/24.  And exact PREFIX (or just PREFIX)
                     selects routes with this exact prefix. If neither of these
                     options are present, ip assumes root 0/0 i.e. it lists the
                     entire table.


              tos TOS

              dsfield TOS
                     only select routes with the given TOS.


              table TABLEID
                     show the routes from this table(s). The default setting is
                     to show table main.  TABLEID may either be the ID of a real
                     table or one of the special values:

                             all - list all of the tables.

                             cache - dump the routing cache.


              vrf NAME
                     show the routes for the table associated with the vrf name


              cloned

              cached list cloned routes i.e. routes which were dynamically
                     forked from other routes because some route attribute (f.e.
                     MTU) was updated.  Actually, it is equivalent to table
                     cache.


              from SELECTOR
                     the same syntax as for to, but it binds the source address
                     range rather than destinations.  Note that the from option
                     only works with cloned routes.


              protocol RTPROTO
                     only list routes of this protocol.


              scope SCOPE_VAL
                     only list routes with this scope.


              type TYPE
                     only list routes of this type.


              dev NAME
                     only list routes going via this device.


              via [ FAMILY ] PREFIX
                     only list routes going via the nexthop routers selected by
                     PREFIX.


              src PREFIX
                     only list routes with preferred source addresses selected
                     by PREFIX.


              realm REALMID

              realms FROMREALM/TOREALM
                     only list routes with these realms.


       ip route flush
              flush routing tables
              this command flushes routes selected by some criteria.


              The arguments have the same syntax and semantics as the arguments
              of ip route show, but routing tables are not listed but purged.
              The only difference is the default action: show dumps all the IP
              main routing table but flush prints the helper page.


              With the -statistics option, the command becomes verbose. It
              prints out the number of deleted routes and the number of rounds
              made to flush the routing table. If the option is given twice, ip
              route flush also dumps all the deleted routes in the format
              described in the previous subsection.


       ip route get
              get a single route
              this command gets a single route to a destination and prints its
              contents exactly as the kernel sees it.


              fibmatch
                     Return full fib lookup matched route. Default is to return
                     the resolved dst entry


              to ADDRESS (default)
                     the destination address.


              from ADDRESS
                     the source address.


              tos TOS

              dsfield TOS
                     the Type Of Service.


              iif NAME
                     the device from which this packet is expected to arrive.


              oif NAME
                     force the output device on which this packet will be
                     routed.


              mark MARK
                     the firewall mark (fwmark)


              vrf NAME
                     force the vrf device on which this packet will be routed.


              ipproto PROTOCOL
                     ip protocol as seen by the route lookup


              sport NUMBER
                     source port as seen by the route lookup


              dport NUMBER
                     destination port as seen by the route lookup


              connected
                     if no source address (option from) was given, relookup the
                     route with the source set to the preferred address received
                     from the first lookup.  If policy routing is used, it may
                     be a different route.


              Note that this operation is not equivalent to ip route show.  show
              shows existing routes.  get resolves them and creates new clones
              if necessary. Essentially, get is equivalent to sending a packet
              along this path.  If the iif argument is not given, the kernel
              creates a route to output packets towards the requested
              destination.  This is equivalent to pinging the destination with a
              subsequent ip route ls cache, however, no packets are actually
              sent. With the iif argument, the kernel pretends that a packet
              arrived from this interface and searches for a path to forward the
              packet.


       ip route save
              save routing table information to stdout
              This command behaves like ip route show except that the output is
              raw data suitable for passing to ip route restore.


       ip route restore
              restore routing table information from stdin
              This command expects to read a data stream as returned from ip
              route save.  It will attempt to restore the routing table
              information exactly as it was at the time of the save, so any
              translation of information in the stream (such as device indexes)
              must be done first. Any existing routes are left unchanged. Any
              routes specified in the data stream that already exist in the
              table will be ignored.


NOTES
       Starting with Linux kernel version 3.6, there is no routing cache for
       IPv4 anymore. Hence ip route show cached will never print any entries on
       systems with this or newer kernel versions.


EXAMPLES
       ip ro
           Show all route entries in the kernel.

       ip route add default via 192.168.1.1 dev eth0
           Adds a default route (for all addresses) via the local gateway
           192.168.1.1 that can be reached on device eth0.

       ip route add 10.1.1.0/30 encap mpls 200/300 via 10.1.1.1 dev eth0
           Adds an ipv4 route with mpls encapsulation attributes attached to it.

       ip -6 route add 2001:db8:1::/64 encap seg6 mode encap segs
       2001:db8:42::1,2001:db8:ffff::2 dev eth0
           Adds an IPv6 route with SRv6 encapsulation and two segments attached.

       ip -6 route add 2001:db8:1::/64 encap seg6local action End.DT46 vrftable
       100 dev vrf100
           Adds an IPv6 route with SRv6 decapsulation and forward with lookup in
           VRF table.

       ip route add 10.1.1.0/30 nhid 10
           Adds an ipv4 route using nexthop object with id 10.
