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:

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?
