The maximum BGP message size is 4096 and there is no padding, so you would need a heck of a lot of overhead to get another 300+ bytes on there. I'd say the answer is no, unless you're running this over a MPLS over GRE over MPLS over IPSec over MPLS over... well... you get the picture. :) It's possible that your link isn't actually capable of passing 4096-ish byte packets for whatever resaon. A quick way to validate or eliminate that theory is to do some pings from the router with different size payloads, sourced from your side of the /30 and pinging the far side, and using the df-bit to prevent fragmentation. Failing that, make sure you aren't doing anything stupid with your control plane policiers, maybe try turning those off to see if there is an improvement. -- Richard A Steenbergen <r...@e-gerbil.net> http://www.e-gerbil.net/ras GPG Key ID: 0xF8B12CBC (7535 7F59 8204 ED1F CC1C 53AF 4C41 5ECA F8B1 2CBC)
