Configuring RIP route redistribution
Network requirements
As shown in Figure 8, Switch B communicates with Switch A through RIP 100 and with Switch C through RIP 200.
Configure RIP 200 to redistribute direct routes and routes from RIP 100 on Switch B so Switch C can learn routes destined for 10.2.1.0/24 and 11.1.1.0/24. Switch A cannot learn routes destined for 12.3.1.0/24 and 16.4.1.0/24.

Configuration procedure
Configure IP addresses for interfaces. (Details not shown.)
Configure basic RIP:
# Enable RIP 100, and configure RIPv2 on Switch A.
<SwitchA> system-view [SwitchA] rip 100 [SwitchA-rip-100] network 10.0.0.0 [SwitchA-rip-100] network 11.0.0.0 [SwitchA-rip-100] version 2 [SwitchA-rip-100] undo summary [SwitchA-rip-100] quit
# Enable RIP 100 and RIP 200, and configure RIPv2 on Switch B.
