Applying a Prefix List for Route Redistribution
To pass traffic through a configured prefix list, use the prefix list in a
route redistribution
command.
Apply the prefix list to all traffic redistributed into the routing process. 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, use the following commands.
• Enter RIP mode.
CONFIGURATION mode
router rip
• Apply a configured prefix list to incoming routes. You can specify an interface.
If you enter the name of a nonexistent prefix list, all routes are forwarded.
CONFIG-ROUTER-RIP mode
distribute-list prefix-list-name in [ interface ]
• Apply a configured prefix list to outgoing routes. You can specify an interface or type of route.
If you enter the name of a non-existent prefix list, all routes are forwarded.
CONFIG-ROUTER-RIP mode
distribute-list prefix-list-name out [ interface | connected | static | ospf]
Example of Viewing Configured Prefix Lists (ROUTER RIP mode)
To view the configuration, use the
show config
command in ROUTER RIP mode, or the
show
running-config rip
command in EXEC mode.
