Configuring single-hop echo detection (for a specific
destination)
Configure this feature when the peer device does not support BFD. When a unidirectional link occurs
between the local device and a specific neighbor, BFD can detect the failure and the local device does
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.
To configure BFD for RIP (single hop echo detection for a specific destination):
Ste
p
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.
The rip bfd enable destination
command and the rip bfd enable
command are mutually exclusive
and cannot be configured on a
device at the same time.
Enabling bidirectional control detection
This feature only works for RIP neighbors that are directly connected (one hop away from each other).
To configure BFD for RIP (bidirectional control detection):
Ste
p
Command Remarks
1. Enter system view.
system-view N/A
2. Create a RIP process and
enter RIP view.
rip [ process-id ] [ vpn-instance
vpn-instance-name ]
By default, RIP is disabled.
3. Specify a RIP neighbor.
peer ip-address
By default, RIP does not unicast
updates to any peer.
4. Enter interface view.
interface interface-type
interface-number
N/A
5. Enable BFD on the RIP
interface.
rip bfd enable Disabled by default.
NOTE:
Because the undo peer command does not remove the neighbor relationship at once, executing the
command cannot bring down the BFD session at once.
