Figure 42 Backup link for H-VPLS with LSP access
The H-VPLS with LSP access activates the backup link when:
• The tunnel over which the primary PW is established is deleted, causing the PW to go down.
• BFD detects a main link failure.
• The LDP session between the peers of the primary PW goes down, and the PW is deleted as a
result.
