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 <na...@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.
