I got an answer for my question. 7018/ATT does ACCEPT /24 routes from 701/mci. e.g 24.143.13.0/24 on route-server.ip.att.net has AS-PATH (7018 701 13368). Is 7018 preferring 19094 over 701 regardless of AS-PATH length? Or, 7018 will not take prefixes from other peers if a particular prefix is coming from 19094 regardless of AS-PATH? ** 7018 is just an example. There a quite a few ISP with the same behavior. Well .. I'm still in the maze. --- Kyaw Khine <joekhine@yahoo.com> wrote:
Says .. I pick 7018/AT&T. 7018 is accepting 701/mci customer routes. But is 7018 accepting 701/mci customer /24 routes ??? 7018 is definitely accepting 19094/telcove /24 routes because I see 64.9.17.0/24 on ATT route-server (route-server.ip.att.net)
So, why is 7018 receiving/accepting /24 from some peers (19094) but not from others (701)???
That .. I can't figure out.
