Usage Guidelines

Usage Scenario

To add a FEC node to a FEC list, run the fec-node command. The FEC list is used to dynamically establish BFD sessions so that the BFD sessions can monitor LDP LSPs that are mapped to FECs in the FEC list. Compared with establishing the BFD sessions that monitor all LSPs, establishing BFD sessions that monitor specified LSPs helps reduce network costs. After a FEC list is created and nodes are added to the list, configure BFD to reference this list.

Prerequisites

A FEC list has been created using the fec-list command.
