Chairs,

During IETF 109, chairs had asked the authors of draft-rathi-mpls-egress-tlv-for-nil-fec
and  draft-nainar-mpls-spring-lsp-ping-sr-generic-sid to discuss the possibility of merging the
drafts as they are addressing same problem space.
Authors of both drafts discussed this and decided to keep the drafts independent
and progress separately due to below reasons.

  1.  Both drafts provide varying level of validation and each one may be independently useful to

different use cases.

  1.  Egress TLV for NIL FEC is generic and applicable to any MPLS protocol

Such as LDP stitching onto SR or SR stitching onto RSVP etc . It provides ping/traceroute

Facilities without having to upgrade transit routers
