Hi Stefano,
The main purpose of the solution is to provide
topology independent local protection using RSVP-TE in widely
deployed LDP based MPLS networks. Link protection is already
deployed using manually configured RSVP-TE one-hop LSPs. This
draft addresses node protection.
Now, the solution can also be used to protect segment routing
hop-by-hop node segments and we would add a note about it.
Of course, the other solution that you mentioned may fit
segment-routing too.
Thanks,
Santosh
