Route Filtering Policies
Sometimes a router may receive many host routes from the same network, which
are not helpful for routing and occupy a large amount of network resources. In
this case, you can disable RIP from receiving host routes to save network resources.
Follow these steps to disable RIP from receiving host routes:
To do...
Enter system view
Enter RIP view
Disable RIP from receiving
host routes
RIPv2 can be disabled from receiving host routes, but RIPv1 cannot.
You can configure RIP to advertise a default route with the specified metric to RIP
neighbors.
Follow these steps to configure RIP to advertise a default route:
To do...
Enter system view
Enter RIP view
Enable RIP to advertise a
default route
The router enabled to advertise a default route does not receive default routes
from RIP neighbors.
Route filtering is supported by the router. You can filter routes by configuring the
inbound and outbound route filtering policies via referencing an ACL and IP prefix
list. You can also specify to receive only routes from a specified neighbor.
Follow these steps to configure a routing policy:
To do...
Enter system view
Enter RIP view
Define a filtering policy
for incoming routes
Use the command...
system-view
rip [ process-id ]
[ vpn-instance
vpn-instance-name ]
undo host-route
Use the command...
system-view
rip [ process-id ]
[ vpn-instance
vpn-instance-name ]
default-route originate
cost value
Use the command...
system-view
rip [ process-id ]
filter-policy { acl-number | gateway
ip-prefix-name | ip-prefix ip-prefix-name
[ gateway ip-prefix-name ] } import
[ interface-type interface-number ]
