10.0.0.0/8 192.168.1.2 1 0 RA 50
10.2.1.0/24 192.168.1.2 1 0 RA 16
10.1.1.0/24 192.168.1.2 1 0 RA 16
The output shows that RIPv2 uses classless subnet mask.
NOTE:
RIPv1 routing information has a long aging time, so it will exist until it ages out after RIPv2 is configured.
Configuring RIP route redistribution
Network requirements
As shown in the following figure:
• Two RIP processes are running on Switch B, which communicates with Switch A through RIP 100
and with Switch C through RIP 200.
• Configure route redistribution on Switch B to make RIP 200 redistribute direct routes and routes from
RIP 100. Switch C can then learn routes destined for 10.2.1.0/24 and 11.1.1.0/24, and Switch A
cannot learn routes destined for 12.3.1.0/24 and 16.4.1.0/24.
• Configure a filtering policy on Switch B to filter out the route 10.2.1.1/24 from RIP 100, making the
route not advertised to Switch C.

Configuration procedure
1. Configure an IP address for each interface. (Details not shown)
2. Configure basic RIP functions.
