Re: Explicit Label Control

["Adrian Farrel" <afarrel@movaz.com>]

Manoj,

Your reading of the drafts is correct, explicit label control is intended to
allow an ERO to include labels for any hop as well as an ultimate label for
egress control.

That O-UNI (currently?) only uses ERO labels for egress control is fine.
