Re: ExaBGP and BIRD clue in the house?

Exactly… It’s not an issue, it’s expected behavior.

If you move the static up within the neighbor definition, it becomes an Anchor Route and Exa knows you want it 
announced.

If you leave it in the static routes section, then you either need a redistribution policy from static to bgp (not 
recommended) or you need some other sort of policy that tells exa that you want to announce the route.

FYI, if the static is moved up within the neighbor definition, it works.   So this is an Exa related issue/feature 
and not a problem with BIRD.

I'll move the noise to the Exa list if needed.

I've reduced it to a simple config:
BIRD:
protocol bgp {
description "ExaBGP-local";
local as 12345;
allow local as 1;
neighbor 10.0.0.2 as 12345;
next hop keep;
start delay time 5;
import all;
export all;
}
EXABGP:
group gixlg {
   hold-time 180;
   local-as 12345;
   router-id 10.0.0.2;
   family {
      ipv4 unicast;
   }
   neighbor 10.0.0.1 {
      router-id 10.0.0.2;
      local-address 10.0.0.2;
      peer-as 12345;
      description "Bird-local";
      group-updates;
   }
   static {
      route 1.2.3.4/32 next-hop 4.3.2.1;
   }
}
Everything comes up.   But bird has no routes.
