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.

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 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:
