This section provides information to configure RIP and examples of common configuration tasks. For a router to accept RIP updates, in the config>router>rip context, you must define at least one group and one neighbor. A router ignores updates received from routers on interfaces not configured for RIP. Configuring other RIP commands and parameters are optional.
By default, the local router imports all routes from this neighbor and does not advertise routes. The router receives both RIPv1 and RIPv2 update messages with 25 to 255 route entries per message.
The RIP configuration commands have three primary configuration levels: rip for global configurations, group group-name for RIP group configurations, and neighbor ip-int-name for RIP neighbor configurations. Within the different levels, the configuration commands are identical. For the repeated commands, the command that is most specific to the neighboring router is in effect; that is, neighbor settings have precedence over group settings which have precedence over RIP global settings.
The minimal RIP parameters that need to be configured in the config>router>rip context are:
group
neighbor
ALA-A>config>router>rip# info
----------------------------------------------
group "RIP-ALA-A"
neighbor "to-ALA-4"
exit
exit
----------------------------------------------
ALA-A>config>router>rip#
