HP VPN Firewall Appliances Network Management Configuration Guide

BFD provides a single mechanism to quickly detect and monitor the connectivity of links between OSPF
neighbors, reducing network convergence time. For more information about BFD, see High Availability
Configuration Guide.
OSPF supports the following BFD detection methods:
Bidirectional control detection, which requires BFD configuration to be made on both OSPF routers
on the link.
Single-hop echo detection, which requires BFD configuration to be made on one OSPF router on the
link.
Configuring bidirectional control detection
Both ends of a BFD session must be on the same network segment and in the same area. One network
segment can only belong to one area.
To enable BFD control packet bidirectional detection on an OSPF interface:
Ste
p
Command
Remarks
1. Enter system view.
system-view N/A
2. Enter interface view.
interface interface-type interface-number N/A
3. Enable BFD bidirectional
control detection on the
interface.
ospf bfd enable
By default, BFD
bidirectional control
detection is disabled.
Configuring single-hop echo detection

Command
Remarks
1. Enter system view.

2. Configure the source address
of echo packets.

By default, the source address of
echo packets is not configured.
3. Enter interface view.

N/A
4. Enable BFD single-hop echo
detection on the interface.
ospf bfd enable echo
By default, BFD single-hop echo
detection is disabled.
