[Idr] Fwd: I-D ACTION:draft-pmohapat-idr-acceptown-community-01.txt

[Danny McPherson <danny at tcb.net>]

Surprisingly, I don't recall seeing this draft discussed here yet.

In short, I think the is a really bad idea.  It's bad enough the route
reflection spec was changed from 1966 to 2796 to permit an RR
to reflect routes to a client even if they were learned from that
client - arguably, to enable an implementation optimization, but
for this to recommend a well-known community and further recommend
disabling RFC 1966 "suppression" on the RR if the BGP community
is present in order to save configuration overhead on the PEs is
going a bit overboard.
