Not configured by default.
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.

Configure the filtering of
outgoing routes.
filter-policy

Not configured by default.
The
filter-policy export
command
filters outgoing routes, including
routes redistributed with the
import-route
command.
Configuring a priority for RIP
Multiple IGP protocols can run in a router. If you want RIP routes to have a higher priority than those
learned by other routing protocols, then assign RIP a smaller priority value to influence optimal route
selection.
To configure a priority for RIP:
Step Command
Remarks
1.
Enter system view.

2.
Enter RIP view.

100 by default.
Configuring RIP route redistribution
If a router runs RIP and other routing protocols, you can configure RIP to redistribute OSPF, IS-IS, BGP,
static, or direct routes.
Only active routes can be redistributed. To display route state information, use the
display ip
routing-table
protocol
command.
To configure RIP route redistribution:
Step Command
Remarks
1.
Enter system view.

2.
Enter RIP view.

3.
Configure a default metric for
redistributed routes.
default cost
value
Optional.
The default metric of a redistributed
route is 0.
