Route Policy Configuration Example
Applying a Route Policy to IPv4 Route Redistribution
Network Requirements
As shown in the following figure, Switch A and Switch B communicate with each other at the network
layer through RIPv2. Switch A has static routes to networks 20.0.0.0/8, 30.0.0.0/8, and 40.0.0.0/8.
Switch B needs to access these networks through Switch A, while Switch A allows Switch B to access
networks 20.0.0.0/8 and 40.0.0.0/8, but not 30.0.0.0/8.
