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.
Table 21 Configuring RIP to Filter Routes
Operation
Configure filtering the received routing
information distributed by the specified
address
Cancel filtering the received routing
information distributed by the specified
address
Configure filtering the received global
routing information
Cancel filtering the received global routing
information
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.
Table 22 Displaying and Debugging RIP
Operation
Display the current RIP state and configuration
information.
Enable the RIP debugging information
Enable the debugging of RIP receiving packet. debugging rip receive
Enable the debugging of RIP sending packet.

the Ethernet port. The Ethernet ports of Switch A and Switch B are connected to
the network 155.10.1.0 and 196.38.165.0. Switch C, Switch A, and Switch B are
connected by Ethernet 110.11.2.0. Correctly configure RIP to ensure that Switch
C, Switch A, and Switch B can interconnect.
