2.5.5 Checking the Configuration

After the configuration of detecting an LDP LSP through a static BFD session, you can view
the BFD configuration, the specified BFD session, and BFD statistics.
Prerequisite
The configurations of the static BFD for LDP LSP function are complete.

2.6 Configuring Dynamic BFD for LDP LSP

By configuring a dynamic BFD session to detect an LDP LSP, you does not need to configure
BFD parameters. This can speed up link fault detection and reduce workload on configurations.

2.6.1 Establishing the Configuration Task

Before configuring a dynamic 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 complete the configuration task quickly and accurately.
Applicable Environment
With dynamic BFD for LDP LSP, failure detection speeds up and the workload of configuring
decreases. In addition, LDP FRR is well supported for the LSP for providing better services.
Pre-configuration Tasks
Before configuring the dynamic BFD for LDP LSP, complete the following tasks:
Issue 04 (2011-12-26)
The default value is 3.
Run the quit command to return to the system view.
Run the bfdcfg-name command to enter the BFD session view.
Run the display bfd configuration { all | static } command to check the BFD configuration.
Run the display bfd session { all | static } command to check information about the BFD
session.
Run the display bfd statistics session { all | static } command to check information about
BFD statistics.
NOTE
When working in LDP LSP, the dynamic BFD supports only the LDP LSP that is created after the host
route is triggered.
