Did the WG consider updating RF C3209? OLD: The node SHOULD be prepared to forward packets carrying the assigned label prior to sending the RESV message. NEW: The node SHOULD be prepared to forward packets carrying the assigned label prior to sending the RESV message. When an ingress LSR receives an RESV message, it MAY/SHOULD/MUST invoke the LSP Self-ping procedures [this-RFC-to-be] to verify that forwarding state has been installed on all downstream nodes.

I see that the Security Considerations section says, "operators SHOULD filter LSP Self-ping packets at network ingress points" I think it would be helpful to have the draft explicitly state the scope for this new function - within a single operator's network is my assumption. If that assumption is not correct, I may come back with more questions. There was also a suggestion made int he SecDir review that you may want to consider: https://mailarchive.ietf.org/arch/search/?email_list=secdir

I was looking at o The UDP Destination Port MUST be lsp-self-ping (8503) [IANA.PORTS] and wondering why this is a MUST. Is the answer that this mechanism works within an administrative domain, so you can just tell the other end what the port number needs to be?
