The output shows that RIPv2 uses classless subnet mask.
NOTE:
RIPv1 routing information has a long aging time, so it will exist until it a

Configuring RIP route redistribution
Network requirements
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, a n d S w i t c h A c a n n o t l e a r n
routes destined for 12.3.1.0/24 and 16.4.1.0/24.
