NOTE:
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. You can disable RIP from receiving host
routes to save network resources.
To disable RIP from receiving host routes:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter RIP view.
rip [ process-id ] [ vpn-instance
vpn-instance-name ]
N/A
3. Disable RIP from receiving host
routes.
undo host-route Enabled by default.
NOTE:
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
interface view takes precedence over 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.
To configure RIP to advertise a default route:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter RIP view.
rip [ process-id ] [ vpn-instance
vpn-instance-name ]
N/A
3. Enable RIP to advertise a default
route. default-route { only | originate }
[ cost cost ]
Optional.
Not enabled by default.
4. Return to system view. quit N/A
5. Enter interface view.
interface interface-type
interface-number
N/A
6. Configure the RIP interface to
advertise a default route.
rip default-route { { only | originate }
[ cost cost ] | no-originate }
Optional.
By default, a RIP interface can
advertise a default route if the
RIP process is configured with
default route advertisement.
