To enable RIP redistribution, enter the following command.
PowerConnect(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.
PowerConnect(config)#interface ethernet 0/1/1
PowerConnect(config-if-e1000-1)#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 Dell PowerConnect device does not advertise a route on the same interface
as the one on which it learned the route.
•
Poison reverse – The Dell PowerConnect 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 RIP maximum valid route cost of 15.
To enable split horizon, enter commands such as the following .
PowerConnect(config)#interface ethernet 0/1/1
PowerConnect(config-if-e1000-1)#no ip rip poison-reverse
Syntax: [no] ip rip poison-reverse
