10.0.0.0/8 1.1.1.2 1 0 RA 9

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

3. Configure a RIP version:

# Configure RIPv2 on Router A.

[RouterA] rip

[RouterA-rip-1] version 2

[RouterA-rip-1] undo summary

[RouterA-rip-1] quit

# Configure RIPv2 on Router B.

[RouterB] rip

[RouterB-rip-1] version 2

[RouterB-rip-1] undo summary

# Display the RIP routing table on Router A.

[RouterA] display rip 1 route

Route Flags: R - RIP, T - TRIP

P - Permanent, A - Aging, S - Suppressed, G - Garbage-collect

10.0.0.0/8 1.1.1.2 1 0 RA 87

10.1.1.0/24 1.1.1.2 1 0 RA 19

10.2.1.0/24 1.1.1.2 1 0 RA 19

The output shows that RIPv2 uses classless subnet mask.

NOTE:

fter RIPv2 is confi

ured, RIPv1 routes might still exist in the routing table until they are aged out.

Configuring RIP route redistribution

Network requirements

As shown in Figure 8, Router B communicates with Router A through RIP 100 and with Router C through

RIP 200.

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

routes destined for 10.2.1.0/24 and 11.1.1.0 / 24 . R o u te r A c a n n o t l e a r n ro 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 Router B to not advertise route 10.2.1.1/24 to Router C.
