Configuring BFD for static routes

IMPORTANT:
Enabling BFD for a flapping route could worsen the situation.
BFD provides a general-purpose, standard, medium-, and protocol-independent fast failure
detection mechanism. It can uniformly and quickly detect the failures of the bidirectional forwarding
paths between two routers for protocols, such as routing protocols and MPLS.
For more information about BFD, see High Availability Configuration Guide.

Bidirectional control mode

To use BFD bidirectional control detection between two devices, enable BFD control mode for each
device's static route destined to the peer.
To configure a static route and enable BFD control mode, use one of the following methods:
• Specify an output interface and a direct next hop.
• Specify an indirect next hop and a specific BFD packet source address for the static route.
To configure BFD control mode for a static route (direct next hop):
Step
Enter system view.
