Session State: Up Session Role: Passive
Template Name: -
The output shows that two BFD sessions have been established between Switch A and Switch C. One
session verifies the connectivity of the LSP from 3.3.3.9/32 to 1.1.1.9/32 and the other session verifies the
connectivity of the LSP from 1.1.1.9/32 to 3.3.3.9/32.
BFD for PW configuration example
Network requirements
Create two LDP PWs to implement PW redundancy between CE 1 and CE 2. The primary PW goes
through PE 1—PE 2. The backup PW goes through PE 1—PE 3. Configure BFD to inspect the connectivity
of the primary PW. When the primary PW fails, CE 1 and CE 2 communicate through the backup PW.
