When the link between Switch C and the Layer 2 switch fails, BFD can quickly detect the link failure
and notify it to RIP, and the BFD session goes down. In response, RIP deletes the neighbor
relationship with Switch C and the route information received from Switch C. Then, Switch A learns
the static route sent by Switch C with the outbound interface being the interface connected to
Switch B.

mode)
Configuration procedure
1) Configure VLAN interfaces.
# Configure Switch A.
<SwitchA> system-view
[SwitchA] interface vlan-interface 100
[SwitchA-Vlan-interface100] ip address 192.168.1.1 24
[SwitchA-Vlan-interface100] quit
[SwitchA] interface vlan-interface 200
[SwitchA-Vlan-interface200] ip address 192.168.2.1 24
[SwitchA-Vlan-interface200] quit
# Configure Switch B.
<SwitchB> system-view
[SwitchB] interface vlan-interface 200
[SwitchB-Vlan-interface200] ip address 192.168.2.2 24
[SwitchB-Vlan-interface200] quit
[SwitchB] interface vlan-interface 300
[SwitchB-Vlan-interface300] ip address 192.168.3.1 24
# Configure Switch C.
<SwitchC> system-view
[SwitchC] interface vlan-interface 100
[SwitchC-Vlan-interface100] ip address 192.168.1.2 24
[SwitchC-Vlan-interface100] quit
[SwitchC] interface vlan-interface 300
[SwitchC-Vlan-interface300] ip address 192.168.3.2 24
[SwitchC-Vlan-interface300] quit
2) Configure RIP basic functions.
