Hi,

Sorry to come back on this subject but it is still not clear to me why we
are using different subobject types between XRO and ERO/RRO/IRO in PCEP.

Is there any particular reason?

In http://www.ietf.org/internet-drafts/draft-ietf-pce-pcep-11.txt
     Type   Subobject
        1   IPv4 prefix
        2   IPv6 prefix
        4   Unnumbered Interface ID
       32   Autonomous system number

In http://www.ietf.org/internet-drafts/draft-ietf-pce-pcep-xro-04.txt

        Type           Subobject 
        -------------+------------------------------- 
        1              IPv4 prefix 
        2              IPv6 prefix 
        3              Unnumbered Interface ID 
        4              Autonomous system number 
        5              SRLG


Thanks
Fabien
