Did anyone see BGP flaps this morning at about 07:01 UTC as a result of BGP malformed update? It flapped one of our iBGP sessions: May 20 08:01:51.150 BST: %BGP-3-NOTIFICATION: received from neighbor XXX.XXX.XXX.XXX 3/1 (update malformed) 31 bytes E0281C00 00000000 00000000 00000000 00 Another ISP saw the same thing... code 3 (Update Message Error) subcode 1 (invalid attribute list), Data: e0 28 1c 00 00 00 Is there a new BGP rogue update out there?
