DISCUSS:
----------------------------------------------------------------------

I am balloting DISCUSS because I believe the specification is not clear enough.

(1) The document recommends (5 separate times) that an ID "SHOULD be identical
to the value advertised" in an existing TLV.

If the other TLV is advertised, when is it ok for the values not to be the
same?  Why is this action recommended and not required?

Should the receiver of these TLVs take any action if the values are not
identical?

(2) §3.1: The requirement for the Router ID to be unique within the flooding
scope of the LSP has been removed.

Please help me understand why this change is ok.  If the Router ID can be used
to identify "the router who generates the inter-AS reachability TLV", not
requiring unique values seems to go counter to that idea.
