Use a prefix list for route redistribution

To pass traffic through a configured prefix list, you must use the prefix list in a route redistribution
command. The prefix list is applied to all traffic redistributed into the routing process and the traffic is
either forwarded or dropped depending on the criteria and actions specified in the prefix list.
To apply a filter to routes in RIP (RIP is supported on C and E-Series.), use either of the following
commands in the ROUTER RIP mode:
Command Syntax
router rip
distribute-list
prefix-list-name
[ ]
interface
distribute-list
prefix-list-name
[ |
connected
interface
To view the configuration, use the
example below or the

To apply a filter to routes in OSPF, use either of the following commands in the ROUTER OSPF mode:
