RIP Redistribution Configuring RIP

Creating a Redistribution Filter
Use the ip rip redist-filter command to create a RIP redistribution filter. Enter the command, the route
type, and destination IP address and mask of the traffic you want to redistribute. Only routes matching the
policy and destination specified in the filter will be redistributed into RIP and passed to the destination.
For example to redistribute OSPF routes destined for the 10.0.0.0 network you would enter:
-> ip rip redist-filter ospf 10.0.0.0 255.0.0.0
Note. A network/subnetwork of 0.0.0.0. 0.0.0.0 will redistribute all routes for the configured route type.
Use the no ip rip redist-filter command to delete a filter. For example, to “turn off” redistribution for
OSPF routes to the 10.0.0.0 network you would enter:
-> no ip rip redist-filter ospf 10.0.0.0 255.0.0.0
Use the show ip rip redist-filter command to display the currently-configured redistribution filters.
Note. Local interfaces will not be added to the RIP routing table unless RIP redistribution is enabled and a
filter is added for the local protocol.
Configuring a Redistribution Filter Action
By default, redistribution filters allow (permit) routes that match the criteria specified in the filter to be
redistributed. However, you can use the redistribution filter action feature to “fine-tune” a filter. You may
want to redistribute all routes to a network except routes destined for a particular subnet. In this case, you
would “permit” all traffic to the network but “deny” traffic to a particular subnet.
Use the ip rip redist-filter effect command to configure the redistribution filter action. Enter the
command, specify the route type to be redistributed, enter the destination IP address/mask, then enter
whether to permit redistribution (permit) or deny redistribution (deny).
For example, if you wanted to redistribute all OSPF routes to the 172.22.0.0 network except routes to
subnetwork 3 you would used the following commands:
-> ip rip redist-filter ospf 172.22.0.0 255.255.0.0 effect permit
-> ip rip redist-filter ospf 172.22.3.0 255.255.255.0 effect deny
