Configuring Bfd For Rip (Single-Hop Detection In Bfd Echo Packet Mode) - H3C S5500-EI Configuration Manual

Configuring BFD for RIP (single-hop detection in BFD echo
packet mode)
Network requirements
In the following figure, Switch A and Switch C are interconnected through a Layer 2 switch.
VLAN-interface 100 of the two switches runs RIP process 1, BFD is enabled on VLAN-interface 100 of
Switch A.
Switch A is connected to Switch C through Switch B. VLAN-interface 200 on Switch A runs RIP process
2; VLAN-interface 300 on Switch C, and VLAN-interface 200 and VLAN-interface 300 on Switch B run
RIP process 1.
Configure a static route and enable static route redistribution into RIP on Switch C. Switch A learns the
static route sent by Switch C, the outbound interface of the route is the interface connected to the Layer
2 switch.
Configure BFD so that 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.
