RIP interface additional metric configuration example
Network requirements
As shown in Figure 9, run RIPv2 on all the interfaces of Switch A, Switch B, Switch C, Switch D, and
Switch E.
Switch A has two links to Switch D. The link from Switch B to Switch D is more stable than that from
Switch C to Switch D. Configure an additional metric for RIP routes received from VLAN-interface
200 on Switch A so Switch A prefers route 1.1.5.0/24 learned from Switch B.

Configuration procedure
1. Configure IP addresses for interfaces. (Details not shown.)
2. Configure basic RIP:
# Configure Switch A.
<SwitchA> system-view
[SwitchA] rip 1
[SwitchA-rip-1] network 1.0.0.0
[SwitchA-rip-1] version 2
[SwitchA-rip-1] undo summary
[SwitchA-rip-1] quit
# Configure Switch B.
<SwitchB> system-view
[SwitchB] rip 1
[SwitchB-rip-1] network 1.0.0.0
[SwitchB-rip-1] version 2
[SwitchB-rip-1] undo summary
# Configure Switch C.
<SwitchC> system-view
[SwitchB] rip 1
[SwitchC-rip-1] network 1.0.0.0
[SwitchC-rip-1] version 2
[SwitchC-rip-1] undo summary
# Configure Switch D.
Switch B
Switch C
Switch A
Switch D Switch E
