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:
To view the configuration, use the
show config
command in the ROUTER RIP mode (Figure 240) or the
show running-config rip
command in the EXEC mode.
