Configuring Rip Route Redistribution - 3Com 4500G Family Configuration Manual

# Display the RIP routing table of Switch A.
[SwitchA] display rip 1 route
Route Flags: R - RIP, T - TRIP
--------------------------------------------------------------------------
Peer 192.168.1.2
Destination/Mask
10.0.0.0/8
From the routing table, you can find that RIPv1 uses a natural mask.
3) On Switch A and Switch B, specify the RIP version as RIPv2, and disable RIPv2 route automatic
summarization to advertise all subnet routes.
# Configure RIPv2 on Switch A.
[SwitchA] rip
[SwitchA-rip-1] version 2
[SwitchA-rip-1] undo summary
# Configure RIPv2 on Switch B.
[SwitchB] rip
[SwitchB-rip-1] version 2
[SwitchB-rip-1] undo summary
# Display the RIP routing table on Switch A.
[SwitchA] display rip 1 route
Route Flags: R - RIP, T - TRIP
--------------------------------------------------------------------------
Peer 192.168.1.2
Destination/Mask
10.0.0.0/8
10.2.1.0/24
10.1.1.0/24
From the routing table, you can see RIPv2 uses classless subnet mask.
Since the routing information advertised by RIPv1 has a long aging time, it will still exist until it ages out
after RIPv2 is configured.

As shown in the following figure:
Two RIP processes are running on Switch B, which communicates with Switch A through RIP 100
and with Switch C through RIP 200.
