From the routing table, you can see RIP-2 uses classless subnet mask.

Since RIP-1 routing information has a long aging time, it will still exist until aged
out after RIP-2 is configured.
Configuring RIP Route
Redistribution
Network requirements
As shown in Figure 78, two RIP processes are running on Switch B, which
communicates with Switch A through RIP100 and with Switch C through RIP 200.
Configure route redistribution on Switch B, letting the two RIP processes
redistribute routes from each other. Set the cost of redistributed routes from RIP
200 to 3. Configure a filtering policy on Switch B to filter out the route
192.168.4.0/24 from RIP200, making the route not advertised to Switch A.

Configuration procedure
1 Configure an IP address for each interface (Omitted).
2 Configure basic RIP functions.
