.. clicmd:: neighbor A.B.C.D
Specify RIP neighbor. When a neighbor doesn't understand multicast, this
command is used to specify neighbors. In some cases, not all routers will be
able to understand multicasting, where packets are sent to a network or a
group of addresses. In a situation where a neighbor cannot process multicast
packets, it is necessary to establish a direct link between routers. The
neighbor command allows the network administrator to specify a router as a
RIP neighbor. The `no neighbor a.b.c.d` command will disable the RIP
neighbor.
Specify a RIP neighbor to send updates to. This is required when a neighbor
is connected via a network that does not support multicast, or when it is
desired to statically define a neighbor. RIP updates will be sent via unicast
to each neighbour. Neighbour updates are in addition to any multicast updates
sent when an interface is not in passive mode (see the `passive-interface`
command). RIP will continue to process updates received from both the
neighbor and any received via multicast. The `no neighbor a.b.c.d` command
will disable the RIP neighbor.
Below is very simple RIP configuration. Interface `eth0` and interface which
address match to `10.0.0.0/8` are RIP enabled.
