BFD detection for MPLS LDP

[jigojar]

Hi Genius,

 is their any mechanism to identify the MPLS LDP label drop. BFD can help to detect the MPLS LDP drop?

Hello,

You can consider IGP<->LDP sync:

https://www.cisco.com/c/en/us/td/docs/routers/xr12000/software/xr12k_r4-2/mpls/configuration/guide/b_mpls_cg42xr12k/b_mpls_cg42xr12k_chapter_01.html#con_1147847

IGP will watch for LDP having the label on protected link. If none - IGP will poison the link with high metric to avoid.

I hope it solves your question.
