RE: I-D ACTION:draft-ietf-ccamp-tracereq-04.txt

["Hamid Ould-Brahim" <[e-mail]>]

Ron,

This is a good document. I just have one clarification/comment:

in the draft: 

"7) Support the following tunneling technologies: GRE, MPLS, IPSEC,
      GMPLS, IP-in-IP, L2TP. Be easily extensible to support new tunnel
      technologies."

and req. 8 on heterogeneous tunnels.

I assume the tracing doesn't preclude the case where the IP
tunnels are carrying MPLS-in-IP or MPLS-in-GRE encapsulation.

Should that be explicitly mentioned (since it has implication
on the type)?.

Hamid.
