Yeah, that was basically the "route" I had been going through. I have two upstream ISPs that get my routes fine, and that I get the routes from them fine. But I tried probably 20 different bird config versions (using pipes, filters on the pipes, not using pipes, filters on the table itself, and he never got anything to show up.
I think I'm just going to maybe call it a problem on his end, maybe his cisco router was not set to accept my ASN or something I guess. Just seems weird, curious if there was something basic that I was overlooking. But it doesn't sound like it.
The intercepting of packets was a good call for troubleshooting too, but the client already moved on. I was just trying to do a postmortem on the situation to see if it really was my fault for some reason.
I actually think I'm going to pick up an old Cisco switch and set up a BGP session between it and my bird router on that port, just to be 100% sure that everything was set up right on my side. If I do find anything though I'll pass it along.

I would check the basics... do you have a route for the networks you are
exporting? The cisco router has a route to the gateway of the exported
networks. From where came the routes (from the router itself or you learn
it from another procotol/peer)?
