Thanks Neale for responding. “HA LSP” – I was referring to primary LSP (Label Switching Path) and backup LSP. There can be two or more label encaps configured as a group for each label-level in the packet header. In that configuration group, one label will refer to primary next-hop and others will refer to backup next-hops. The backup label will be used if primary next-hop fails for some reason. And this protection-group can be extended to all the label-levels in the label-stack in the packet header.
Hope this is clear (on a high-level, it talks about label protection and support the protection hierarchically for all the label-levels in the label stack in the packet header).

I don’t know what a HA LSP would be. Here’s the docs on what fast convergence support there is: https://github.com/FDio/vpp/blob/master/docs/gettingstarted/developers/fib20/fastconvergence.rst [github.com]<https://urldefense.com/v3/__https:/github.com/FDio/vpp/blob/master/docs/gettingstarted/developers/fib20/fastconvergence.rst__;!!OSsGDw!b_tQQAd3G8uc4uuGWxUD76doCnD_dEmX62U6vRm-ZHAtHvU_SwPLyFBFTX2Pvg$> /neale From: vpp-dev@lists.fd.io <vpp-dev@lists.fd.io> on behalf of Gudimetla, Leela Sankar via lists.fd.io <lgudimet=ciena....@lists.fd.io> Date: Wednesday, 14 July 2021 at 20:57 To: vpp-dev@lists.fd.io <vpp-dev@lists.fd.io> Subject: [vpp-dev] MPLS protection Hello, I am trying out MPLS configurations to test what all features are supported currently on stable 1908. I don’t see protection for LSP like HA or FRR support explicitly. So I am wondering if it is supported yet. Or I may be missing something. Can someone please share (documentation, code) what all protection mechanism supported for MPLS? Thanks, Leela sankar
