Configuring BFD for static routes

Bidirectional forwarding detection (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. For more
information about BFD, see High Availability Configuration Guide.
A dynamic routing protocol notifies BFD of its neighbor information. BFD uses such information to
establish sessions with neighbors by sending BFD control packets. Static routing has no neighbor
discovery mechanism. This section describes how static routing implements BFD.

BFD control mode

To use BFD bidirectional control detection between two devices, you must enable BFD control mode for
each device's static route destined to the peer.
To configure a static route and enable BFD control mode for it, specify an output interface and a direct
next hop, or 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.

2. Configure BFD
control mode for a
static route.
To configure BFD control mode for a static route (indirect next hop):
Step
1. Enter system view.
