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.
