Hello, everyone:

According to section 2.6 of draft-ietf-mpls-rsvp-lsp-tunnel-08.txt and
RFC2210, MTU should be getten from ASPEC if Integrated Services object
is presented in Path msg.

On the other hand, ASPEC is an OPTIONAL object according to RFC2205 and
section 3.1
of draft-ietf-mpls-rsvp-lsp-tunnel-08.txt.

My quesions are:

1. In the case of Integrated Service Tspec is presented in Path msg, is
ASPEC still OPTIONAL?
2. If the answer of above question is YES, how do we manage the Path MTU

if ASPEC is not presented in Path msg?

Thanks for your answer!

Best Regards!
