Disabling Host Route Reception; Advertising A Default Route - H3C LS-3100-52P-OVS-H3 Operation Manual

You need to disable RIPv2 route automatic summarization before advertising a summary route on an
interface.

Disabling Host Route Reception

Sometimes a router may receive from the same network many host routes, which are not helpful for
routing and consume 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.

Advertising a Default Route

You can configure RIP to advertise a default route with a specified metric to RIP neighbors.
In RIP view, you can configure all the interfaces of the RIP process to advertise a default route; in
interface view, you can configure a RIP interface of the RIP process to advertise a default route.
The latter takes precedence over the former on the interface.
If a RIP process is enabled to advertise a default route, to disable an interface of the RIP process
from default route advertisement, you can use the rip default-route no-originate command on the
interface.
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
Return to system view
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 { only | originate }
