The output shows that RIPv2 uses classless subnet mask.

NOTE:

1374BNetwork requirements

As shown in 2554HFigure 251, Firewall communicates with Router A through RIP 100 and with Router B through

RIP 200.

Configure RIP 200 to redistribute direct routes and routes from RIP 100 on Firewall so Router B can learn

routes destined for 10.2.1.0/24 and 11.1.1.0 / 24 . Ro u t e r A c a n n o t l e a r n r o u t e s d e s t i n e d f o r 12. 3.1.0 / 24

and 16.4.1.0/24.

Configure Firewall to not advertise route 10.2.1.1/24 to Router B.
