At least at this stage no special communities are visible but I don't know =

Betreff: RE: Need BGP route check (UPDATE)
From responses I received, I have gotten a number of different answers. Som=
e are seeing our routes from 6128, some from 46887 and a few from both. The=
response from Eric though was typical. Showing the IPv4 prefix only from A=
S6128, but the IPv6 from both 6128 & 46887.=20
I am guessing that 46887 might be set with a community to not export our IP=
v4 prefixes except to direct peers? Anyone directly peered with 46887 that =
could see the community for 129.77.0.0/16 and verify?
