Hi, I did OPS-DIR review fordraft-ietf-mpls-self-ping-05 Summary document is in good shape and ready for publication. However, when I read (in the abstract and also in the text itself): When certain RSVP-TE optimizations are implemented, ingress LSRs can receive RSVP RESV messages before forwarding state has been installed on all downstream nodes. And I then see that this document describes an extra protocol (self-ping) in order to correct that problem, then I really wonder why one would not change: Referring to any LSR, RFC 3209 says, ""The node SHOULD be prepared to forward packets carrying the assigned label prior to sending the RESV message". However, RFC 3209 does not strictly require this behavior. Why not make the SHOULD in RFC3209 a MUST ?? Does the additional self-ping not add a similar delay as that what is avoided with a SHOULD??
