In some special cases, the router can receive a lot of host routes from the same segment, and these 

routes are of little help in route addressing but consume a lot of network resources. After a router is 

disabled from receiving host routes, it can refuse any incoming host route. 

Follow these steps to disable the router from receiving host routes: 

Enter system view 

— 

Enter RIP view 

rip

The route filtering function provided by a router enables you to configure inbound/outbound filter policy 

by specifying an ACL, address prefix list, or route policy to make RIP filter incoming/outgoing routes. 

Besides, you can configure RIP to receive only the RIP packets from a specific neighbor.  

Follow these steps to configure RIP to filter incoming/outgoing routes: 

Enter system view 

— 

Enter RIP view
