Yesterday the full table broke 999,999 prefixes around 14:30 utc. It may be just pure coincidence, but given the timing there may be correlation. On Tue, May 20, 2025 at 9:32 AM Simon Lockhart via NANOG < nanog@lists.nanog.org> wrote:
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?
