i believe (received-only) means that bgp soft-reconfiguration is configured
for the peer and since some policy is denying the route, it won't be used ..
unless a policy change occurs.
here's what we're currently hearing from you folks...
peer1.sjc1#sh ip bgp re 6180
BGP table version is 2830358, local router ID is 207.240.24.10

and it appears as though routing via alternet is working for the networks you
