The output shows that RIPv1 uses natural mask to advertise routing information.

Configuring RIP route redistribution at the CLI
Network requirements
As shown in Figure 244:
Two RIP processes are running on Firewall B, which communicates with Firewall A through RIP 100
and with Firewall C through RIP 200.
Configure RIP 200 to redistribute direct routes and routes from RIP 100 on Firewall B. Firewall C can
then learn routes destined for 10.2.1.0/24 and 11.1.1.0/24, and Firewall A cannot learn routes
destined for 12.3.1.0/24 and 16.4.1.0/24.
Configure a filtering policy on Firewall B to filter out the route 10.2.1.1/24 from RIP 100, making the
route not advertised to Firewall C.
