This would also imply that the AS-path is identical, which will often
not be the case with ECMP between different AS. Nevertheless, I would
urge people to consider ECMP across different AS something only to do
if a CCIE lab scenario requires it. I've never heard anyone mention
multisystem ECMP as a good idea in the IETF or NANOG, and indeed have
heard it condemned.
