Configuration procedure
1 Configure an IP address for each interface (Omitted)
2 Configure basic RIP functions
# Configure Router A.
<RouterA> system-view
[RouterA] rip
[RouterA-rip-1] network 1.0.0.0
[RouterA-rip-1] network 2.0.0.0
[RouterA-rip-1] network 3.0.0.0
# Configure Router B.
<RouterB> system-view
[RouterB] rip
[RouterB-rip-1] network 1.0.0.0
[RouterB-rip-1] network 10.0.0.0
# Display the RIP routing table on Router A.
Route Flags: R - RIP, T - TRIP
P - Permanent, A - Aging, S - Suppressed, G - Garbage-collect
--------------------------------------------------------------------------
Peer 1.1.1.2 on Ethernet1/0
Destination/Mask
10.0.0.0/8
From the routing table, you can see RIP-1 uses natural mask to advertise routing
information.
3 Configure RIP version
# Configure RIP-2 on Router A.
[RouterA] rip
[RouterA-rip-1] version 2
[RouterA-rip-1] undo summary
# Configure RIP-2 on Router B.
[RouterB] rip
[RouterB-rip-1] version 2
[RouterB-rip-1] undo summary
# Display the RIP routing table of Router A.
[RouterA] display rip 1 route
Route Flags: R - RIP, T - TRIP
P - Permanent, A - Aging, S - Suppressed, G - Garbage-collect
--------------------------------------------------------------------------
Peer 1.1.1.2 on Ethernet1/0
Destination/Mask
10.0.0.0/8
10.1.1.0/24
10.2.1.0/24
From the routing table, you can see RIP-2 uses classless subnet mask.
