2.5 Configuring Static BFD for LDP LSP

By configuring a static BFD session to detect an LDP LSP, you can detect LSP connectivity
according to specified parameters.

2.5.1 Establishing the Configuration Task

Before configuring a static BFD session to detect an LDP LSP, familiarize yourself with the
applicable environment, complete the pre-configuration tasks, and obtain the required data. This
can help you rapidly and correctly finish the configuration task.

2.5.2 Enabling Global BFD Function

You need to only enable BFD on both ends of the link to be detected.
Context
Do as follows on each LSR on both ends of a link that to be detected:
Issue 04 (2011-12-26)
BFD can be bound only on the ingress of LDP LSP.
One LSP can be bound to only one BFD session.
The detection only supports the LDP LSP that is triggered to establish by the host route.
