Any responsible ISP should kick you off the net for announcing AS path containing ASNs without permission from the real owner/assignee.
And it also makes clear why it didn't pop up in GRH, as when you insert the GRH ASN 8298 it won't be announced to GRH and thus it doesn't get detected and as quite a number of people check only there it can go quite unnoticed in the IPv6 tables...* Sidetracking: BGP should never accept a path from another peer containing the ASN of a directly connected peer... does it or not? Greets, Jeroen * = every path above 12, aspath sets get decompressed, get listed as a possible ghost so it would pop up.
