Configuring RIP
The following commands deny redistribution of all routes except routes for 10.10.10.x and
10.20.20.x.
Brocade(config-rip-router)#deny redistribute 64 static address 255.255.255.255
255.255.255.255
Brocade(config-rip-router)#permit redistribute 1 static address 10.10.10.0
255.255.255.0
Brocade(config-rip-router)#permit redistribute 2 static address 10.20.20.0
255.255.255.0
Enabling redistribution
After you configure redistribution parameters, you must enable redistribution.
To enable RIP redistribution, enter the following command.
Brocade(config-rip-router)#redistribution
Syntax: [no] redistribution
Enabling learning of default routes
By default, the software does not learn RIP default routes.
To enable learning of default RIP routes, enter commands such as the following.
Brocade(config)#interface ethernet 1/1/1
Brocade(config-if-e10000-1/1/1)#ip rip learn-default
Syntax: [no] ip rip learn-default
Changing the route loop prevention method
RIP can use the following methods to prevent routing loops:
Split horizon – The Brocade device does not advertise a route on the same interface as the one
on which it learned the route.
Poison reverse – The Brocade device assigns a cost of 16 (“infinite” or “unreachable”) to a
route before advertising it on the same interface as the one on which it learned the route. This
is the default.
NOTE
These methods are in addition to the RIP maximum valid route cost of 15.
To enable split horizon, enter commands such as the following.
Brocade(config)#interface ethernet 1/1/1
Brocade(config-if-e10000-1/1/1)#no ip rip poison-reverse
Syntax: [no] ip rip poison-reverse
