Re: RSVP-TE: specifying links in EROs

David,

Tony is right (again).

You may want to take your discussion to the CCAMP WG where an I-D of what
addresses to use when in MPLS-TE/GMPLS is being put together based on
interop experience. The I-D covers EROs. It is still up for discussion.

Cheers,
Adrian
