Below is snap shot of the neighbor in question.
Datagrams (max data segment is 4410 bytes): Rcvd: 6 (out of order: 0), with data: 4, total data bytes: 278 Sent: 6 (retransmit: 5), with data: 2, total data bytes: 4474
Could there be a problem with the total data bytes size exceeds the size of the max data segment?
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 <ras@e-gerbil.net> http://www.e-gerbil.net/ras GPG Key ID: 0xF8B12CBC (7535 7F59 8204 ED1F CC1C 53AF 4C41 5ECA F8B1 2CBC)
