Configuring BFD for OSPF
BFD provides a single mechanism to quickly detect and monitor the connectivity of links between OSPF
neighbors, which improves the network convergence speed. For more information about BFD, see High
Availability Configuration Guide.
OSPF supports the following BFD detection modes:
• Bidirectional control detection—Requires BFD configuration to be made on both OSPF routers on
the link.
• Single-hop echo detection—Requires BFD configuration to be made on one OSPF router on the link.

1. Enter system view.

2. Enter interface view.

3. Enable BFD bidirectional control
detection.
ospf bfd enable
By default, BFD bidirectional
control detection is disabled.
Both ends of a BFD session must be
on the same network segment and
in the same area.

2. Configure the source address of echo
packets.

By default, the source

4. Enable BFD single-hop echo
detection.
ospf bfd enable echo
By default, BFD single-hop
echo detection is disabled.
Configuring OSPF FRR
A link or router failure on a path can cause packet loss and even routing loop until OSPF completes
routing convergence based on the new network topology. FRR enables fast rerouting to minimize the
impact of link or node failures.
