10.0.0.0/8 1.1.1.2 1 0 RA 87

The output shows that RIPv2 uses classless subnet mask.
NOTE:
Because RIPv1 routing information has a long aging time, it will still exist before being aged out after RIPv2
is configured.
Configuring RIP route redistribution at the CLI
Network requirements
As shown in Figure 248 :
• Two RIP processes are running on SecPath B, which communicates with SecPath A through RIP 100
and with SecPath C through RIP 200.
• Configure RIP 200 to redistribute direct routes and routes from RIP 100 on SecPath B. SecPath C can
then learn routes destined for 10.2.1.0/24 and 11.1.1.0/24, and SecPath A cannot learn routes
destined for 12.3.1.0/24 and 16.4.1.0/24.
• Configure a filtering policy on SecPath B to filter out the route 10.2.1.1/24 from RIP 100, making the
route not advertised to SecPath C.
