Hi jl3128,
I noted in the first post that I did try to check the debugs and that’s how I initially noticed only one prefix was actually getting sent out in an UPDATE message. I tried enabling all of the debugging options however there seems to be nothing new in there.
It shows the BGP session initiating, keepalive going back and force, received messages from my neighbor and then one UPDATE message sent from my end with no indication of any errors or issues.
Here is the whole snippet in case I’m missing something however.

I tried using the latest Vyatta image and there is similar behavior - the UPDATE message is malformed but carrying both prefixes so none of them get announced. In VyOS only the single one gets announced.
There was nothing new in the logs while running the Vyatta image except there was now no UPDATE messages.
I’m a bit baffled by this - I believe this was working in a older Vyatta version.
