RFC8654 Extended Message Support for BGP

Tue Dec 08, 2020 5:22 am

https://tools.ietf.org/html/rfc8654

I have a BGP neighbor that occasionally generates messages larger than 4096 bytes, causing the session to flap.
22:21:40 route,bgp,error Message length out of range 19..4096 
22:21:40 route,bgp,error     RemoteAddress=X.X.X.X 
22:21:40 route,bgp,error     MessageLength=4198 
22:22:00 route,bgp,info Connection opened by remote host 
22:22:00 route,bgp,info     RemoteAddress=X.X.X.X
(RouterOS 6.46.3)

Technically, this is a protocol violation by the neighbor. But an implementation of RFC8654 would fix the issue. Any chance we could get support for this?
