RIP parameter configuration
To enable learning of default RIP routes on a global basis, enter the following command.
Brocade(config-rip-router)#learn-default
Syntax: [no] learn-default
To enable learning of default RIP routes on an individual interface basis, enter commands such as
the following.
Brocade(config)#interface ethernet 0/1/1
Brocade(config-if-0/1/1)#ip rip learn-default
Syntax: [no] ip rip learn-default
Configuring a RIP neighbor filter
By default, a Brocade Layer 3 Switch learns RIP routes from all its RIP neighbors. Neighbor filters
allow you to specify the neighbor routers from which the Brocade device can receive RIP routes.
Neighbor filters apply globally to all ports.
To configure a RIP neighbor filter, enter a command such as the following.
Brocade(config-rip-router)#neighbor 1 deny any
This command configures the Layer 3 Switch so that the device does not learn any RIP routes from
any RIP neighbors.
Syntax: [no] neighbor <filter-num> permit | deny <source-ip-address> | any
The following commands configure the Layer 3 Switch to learn routes from all neighbors except
192.168.1.170. Once you define a RIP neighbor filter, the default action changes from learning all
routes from all neighbors to denying all routes from all neighbors except the ones you explicitly
permit. To deny learning from a specific neighbor but allow all other neighbors, you must add a
filter that allows learning from all neighbors. Be sure to add the filter to permit all neighbors last
(the one with the highest filter number). Otherwise, the software can match on the permit all filter
instead of a filter that denies a specific neighbor, and learn routes from that neighbor.
Brocade(config-rip-router)#neighbor 2 deny 192.16.1.170
Brocade(config-rip-router)#neighbor 1024 permit any
Denying route advertisements for connected routes
By default, RIP advertises all connected routes to neighboring routers except for the management
route. To configure the router to not advertise connected routes, use the dont-advertise-connected
command. When the dont-advertise-connected command is configured, the router only sends RIP
enabled interface routes.
To configure the dont-advertise-connected command under the router RIP configuration level, enter
the router rip command.
FastIron(config)#router rip
FastIron(config-rip-router)#dont-advertise-connected
Syntax: [no] dont-advertise-connected
To disable the configuration, use the no form of the command.
