This draft extends MVPN PTA mLDP support to IGP MT and Flex Algo FAD using LDP
MT extension RFC 7307.

I believe this specification would be very helpful for operators using mLDP and
deployment  of Flex Algo for low latency FAD path or IGP MT path as well as
network slicing now being MT aware for MVPM PTA.

I have provided a review of the draft July 2022 and my recommendation was to
separate the mLDP extension to support OSPF and ISIS MT RFC 4915 and RFC 5120
respectively from Flex Algo as it would make the solution to extend Flex Algo
support simpler as it would not be on the base LDP multi topology extension RFC
7307.

I discussed this draft at IETF 114 in person with authors Mankamana and other
authors and came to an agreement that as we want to be able to provide the  MT
awareness to both IGP MT as well as FA ubiquitously that using RFC 7307 and
proposed solution to extend the FEC element to support MT and FA encoding is
the best solution.

This draft is well written and is ready for publication.

Thank you

Gyan
