Configuring single-hop echo detection (for a specific destination)

When a unidirectional link occurs between the local device and a specific neighbor, BFD can detect the failure. The local device will not receive or send any RIP packets through the interface connected to the neighbor to improve convergence speed. When the link recovers, the interface can send RIP packets again.

This feature applies to RIP neighbors that are directly connected.

To configure BFD for RIP (single hop echo detection for a specific destination):

Step

Command

Remarks

1. Enter system view.

system-view

N/A

2. Configure the source IP address of BFD echo packets.

bfd echo-source-ip ip-address

By default, no source IP address is configured for BFD echo packets.

3. Enter interface view.

interface interface-type interface-number

N/A

4. Enable BFD for RIP.

rip bfd enable destination ip-address

By default, BFD for RIP is disabled.
