and does not receive or send any packets on GigabitEthernet 2/1/2. When the route learned from

Router A ages out, Router B uses the route destined for 100.1.1.1/24 through GigabitEthernet 2/1/2.

Configuration procedure

1. Configure IP addresses for interfaces. (Details not shown.)

2. Configure basic RIP and enable BFD on the interfaces:

# Configure Router A.

<RouterA> system-view

[RouterA] rip 1

[RouterA-rip-1] network 192.168.2.0

[RouterA-rip-1] import-route static

[RouterA-rip-1] quit

[RouterA] interface gigabitethernet 2/1/2

[RouterA-GigabitEthernet2/1/2] rip bfd enable destination 192.168.2.2

[RouterA-GigabitEthernet2/1/2] quit

# Configure Router B.

<RouterB> system-view

[RouterB] rip 1

[RouterB-rip-1] network 192.168.2.0

[RouterB-rip-1] network 192.168.3.0

[RouterB-rip-1] quit

# Configure Router C.

RouterC> system-view

[RouterC] rip 1

[RouterC-rip-1] network 192.168.3.0

[RouterC-rip-1] import-route static cost 3

[RouterC-rip-1] quit

3. Configure BFD parameters on GigabitEthernet 2/1/2 of Router A.

[RouterA] bfd echo-source-ip 11.11.11.11

[RouterA] interface gigabitethernet 2/1/2

[RouterA-GigabitEthernet2/1/2] bfd min-echo-receive-interval 500

[RouterA-GigabitEthernet2/1/2] quit

4. Configure static routes:

Router B

Router A

Router C

GE2/1/1

192.168.2.2/24

GE2/1/2

192.168.3.1/24

GE2/1/2

192.168.3.2/24
