I support WG adoption of this draft.

I think this procedure of using TI-LFA post computation backup path
topology independently versus using LFA which is topology dependent makes
the secondary path failover work in cases where the secondary path does not
exist or due to costing is not used.

Question for authors?

Can this enhancement to MoFRR to use TI-LFA local protection for secondary
UMH be applicable to MPLS as well?

Also as TI-LFA local protection for MoFRR secondary UMH applicability to
SR-MPLS data plane as well as SRv6, could there be a possible standards
track draft in Spring for this new solution.

Kind Regards

Gyan
