RIP 97
By default, the additional routing metric added to the route when RIP sends the
packet is 1. The additional routing metric when RIP receives the packet is 0.
Configuring Route Filtering
The router provides the route filtering function. You can configure the filter policy
rules by specifying the ACL and ip-prefix for route redistribution and distribution.
To import a route, the RIP packet of a specific router can also be received by
designating a neighbor router.
Perform the following configurations in RIP view.
By default, RIP does not filter received and distributed routing information.
Displaying and Debugging RIP
After configuring RIP, execute the display command in all views to display the RIP
configuration, and to verify the effect of the configuration. Execute the
debugging command in user view to debug the RIP module. Execute the reset
command in RIP view to reset the system configuration parameters of RIP.
