Jakob,

          In that case we would not want the attributes transferred as the middle AS is not part of the existing OAD.

Thanks,
          Jim Uttaro

If two ASes that are part of an OAD are separated by an AS that is not in the OAD, then the internal attributes will not be transferred.
Why don't you invent an ATTR_SET?

Kind Regards,
Jakob

Subject: [Idr] One Administrative Domain using BGP (Fwd: I-D Action: draft-uttaro-idr-bgp-oad-00.txt)
[Individual Participant]


Dear WG:

We just published a draft [1] to propose a new BGP session type called EBGP-OAD.

As the name suggests, it is a session between two different ASNs that belong to the same operator.  Many idr documents call this grouping a Single Administrative Domain, we're calling it One Administrative Domain (OAD).

An EBGP-OAD session combines properties of EBGP and IBGP: it is an EBGP session with the ability to also announce and receivex IBGP-only or non-transitive attributes.

I'm sure this first version needs some more work, so we would really appreciate comments on the list.  We have requested agenda time at IETF 116, but, as we all know, that may be tight.

Thanks in advance!


Alvaro.
