Yea, I did try that on that test prefix but it just stuck around anyway.. I don't care too much, its just some stale test prefix.
Sadly, I now see it again with 2620:6e:a002::/48, which, somewhat more impressively, is now generating a routing loop Ashburn <-> NYC, and has always been announced from other places has was dropped/re-announced as wel.
Must just be something with my particular prefixes, oh well. Matt On 11/15/20 10:40 PM, Olivier Benghozi wrote:
Probably a ghost route. Such thing happens :( https://labs.ripe.net/Members/romain_fontugne/bgp-zombies Their (nice) LG shows that it's still advertised from a router of theirs in Frankfurt (iBGP next hop ::ffff:2.255.251.224 – so by the way they use 6PE). Your best option would probably be to re-advertise the exact same prefix, then re-withdraw it, then yell at Telia's NOC if it fails... Some years ago we experienced something similar (it was a router of TI Sparkle still advertising a prefix of us in Asia to their clients, that they were previously receiving from our former transit GTT – we were advertising it in Europe...).Le 16 nov. 2020 à 02:58, Matt Corallo <nanog () as397444 net> a écrit : Has anyone else experienced issues where Telia won't withdraw (though will happily accept an overriding) prefixes for the past week, at least? eg 2620:6e:a003::/48 was a test prefix and should not now appear in any DFZ, has not been announced for a few days at least, but shows up in Telia's LG and RIPE RIS as transiting Telia. Telia's LG traceroute doesn't of course, go anywhere, traces die immediately after a hop or with a !N. Wouldn't be a problem except that I needed to withdraw another route due to a separate issue which wouldn't budge out of Telia's tables until it was replaced with something else of higher pref. Matt
