I'm working in a complex BGP environment on Juniper MX480s. We have many peers in various routing instances advertising prefixes to us, and then we advertise a subset of those prefixes to a subset of the other peers. There are various import and export policies controlling our advertisements.

Is there an easy way to see all the peers to whom we are advertising a given network, say 198.51.100.0/24?

I know I can use show route 198.51.100.0/24 advertising-protocol bgp [peer] for each individual peer, but I'd like to check them all in one go.

I'm not aware of any JunOS command to achieve this. Judging by your problem description I guess that you have per peer export policies, not just a few policies, one per peer group.

If the list of peers is large enough, I'd consider scripting something using Juniper's python libraries or just by screen scraping SSH output.

  • Yeah, if I have to do it more than once or twice, I'm going to use PyEZ to find all peers and loop through them to get advertised routes. I was just hoping to get it done quick and easy. – P1h3r1e3d13 Nov 21 '18 at 0:47
