Dear Authors,
I have a minor question, see inline.

8.4.1.1.1 Auto-Derivation from the Ethernet Tag ID

   The following is the procedure for deriving the RT attribute
   automatically from the Ethernet Tag ID associated with the
   advertisement:

        +    The Global Administrator field of the RT MUST
             be set to the Autonomous System (AS) number that the PE
             belongs to.

Vincent:  Here Global Administrator field contains a 2 octets long number, but the Autonomous System (AS) number could be 4 octets, how to handle such case?

        +    The Local Administrator field of the RT contains a 4
             octets long number that encodes the Ethernet Tag-ID. If the
             Ethernet Tag-ID is a two octet VLAN ID then it MUST be
             encoded in the lower two octets of the Local Administrator 
             field and the higher two octets MUST be set to zero.


Regards,
Vincent
