10.0.0.0/8 192.168.1.2 1 0 RA 11
The output shows that RIPv1 uses a natural mask.

Peer 192.168.1.2 on Vlan-interface100
Destination/Mask Nexthop Cost Tag Flags Sec
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
Two RIP processes, as shown in Figure 11 , 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, while 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 route 10.2.1.1/24 from RIP 100, making the route not
advertised to Switch C.
