Configuring a Priority
for RIP
Configuring RIP Route
Redistribution
Optimizing the RIP
Network
To do...
Define a filtering policy
for outgoing routes
n
Using the filter-policy import command filters incoming routes. Routes not
■
passing the filtering will be neither installed into the routing table nor
advertised to neighbors.
Using the filter-policy export command filters outgoing routes, including
■
routes redistributed with the import-route command.
Multiple IGP protocols may run in a router. If you want RIP routes to have a higher
priority than those learned from other routing protocols, you should assign RIP a
smaller priority value to influence optimal route selection.
Follow these steps to configure a priority for RIP:
To do...
Enter system view
Enter RIP view

Follow these steps to configure RIP route redistribution:
