Hi
Iljitsch,
Its a pitty that
this document didn't got airtime anymore today at the v6ops
meeting.
I had a quick hack
read trough this document and have some thoughts to
ventilate:
1) The suggestion to
use community in the way proposed is quite controversial in the way communities
are currently used on the internet. They are typically not sent from ISP to ISP
to ISP etc... In most cases community simply stays within AS itself
(there are some exeptions, but that is typically just between
peers)
2) I do not like
that statement that default behaviour should change in order to sent this
'multihoming' community by default even if the community exchange is not
explicitly enabled. This changes basic default BGP routing behaviour and
implicitly assumes that everybody wants to do this?
3) If the goal
is to have information with the BGP NLRI about its origin, would it not be
better in that case to create a new value for the origin attribute in addition
to the IGP, EGP and unknown values? (This would at least give back some
degree of usage of this attribute)
Brgds,
G/
