In most reasonable scenarios I'd say that this qualifies as too many.
---------------------------------------------
Yeah, technically, but it was not 256 or something where I'd expect an issue to happen. Just curious as to why only that ASN caused the buffer overflow messages as I got them from no other AS ever and wondered if anyone else has seen them. Other ASNs almost certainly have sent 250+ prepends to me before, but they did not cause the overflow. Like I said, I have a ticket open because I am curious:
BGP-WARNING-tBgp4RouteInvalid-2007 <stuff> Route invalid reason - Cannot add/prepend AS-path. Buffer overflow\nNRLI - <prefix> where prefixes are several and different lengths.
Probably nothing, but I always look into stuff I see in the syslog server's router.log.
