I just reset their session after making doubly sure it was configured
for communities, but:
Rtr1#sh bgp ipv6 2001:610:240::/42
BGP routing table entry for 2001:610:240::/42, version 2289519
Paths: (4 available, best #1, table Global-IPv6-Table)
Flag: 0x820
Not advertised to any peer
3333, (aggregated by 3333 193.0.0.56), (received & used)
2001:7F8:1::A500:3333:1 from 2001:7F8:1::A500:3333:1 (193.0.0.56)
Origin IGP, localpref 100, valid, external, best
I don't see any communities there. I get that path also from another
peer with identical configuration, and that does get some communities
set by that peer, so I have reason to suspect that AS3333 does not set
any communities when announcing that route to its peers.

Not much hard-to-renumber infrastructure in there yet, as far as I know
- no IANA to petition, no /etc/namedb/named.root or /etc/bind/db.root
(pick your poison) to replace on each and every machine worldwide...
