[c-nsp] BGP advert problem...

[Chris Hale]

All -

I'm having an issue with a new customer's BGP advertisement.  I'm receiveing
their advert w/o issue, but for whatever reason, my 7206 won't advert to my
upstreams.  I have about 12 BGP peers on this router with no problems, but
for whatever reason, this ONE route won't advertise.  The neighbor in
question is 67.111.165.34, AS27498, advertising 67.110.152.0/24 to us.

216.57.129.81 is one of our upstream peers - no advertisement of
67.110.152.0/24???
