Dear All

Just wondering if anyone else saw this yesterday afternoon ?

Jun 20 16:57:29:E:BGP: From Peer 38.X.X.X received Long AS_PATH= AS_SEQ(2) 174 12956 23456 23456 23456 23456 23456 23456 23456 23456 23456 23456 23456 23456 23456 23456 23456 23456 23456 23456 23456 23456 23456 23456 23456 23456 23456 23456 23456 23456 ... attribute length (567) More than configured MAXAS-LIMIT

Someone is having fun, creating weird and wonderful long AS paths based around AS 23456, we saw the same pattern of data from numerous upstream providers.

Kindest Regards,
