Summary: This draft is basically ready for publication, but has nits
that should be fixed before publication.

Comments:

1) As the PROTO write-up already pointed out, the current version
has a normative downward reference to draft-ietf-l3vpn-bgpvpn-auto.
To me it seems this might be changed to informative reference,
but probably someone more familiar with the protocol(s) should
also confirm this.

2) In Section 3.2 the document uses the phrases like "the AC ID is
NULL" to mean that that "AC ID" field is not included in the message
at all. I found this a bit confusing; probably something like "the AC
ID field is omitted" would be clearer?

3) Section 3.2, "If the global ID is derived from a 2-octet AS 
number, then the high-order 4 octets of this 4 octet field MUST 
be set to zero." Should this be "...the high-order 2 octets..."?

4) The document uses RFC 2119 keywords, but does not include
RFC 2119 in the references list.

Best regards,
Pasi
