I have three BIRD routers:

A uses iBGP only

B also only uses iBGP

C uses eBGP and iBGP

They are connected as follows:

A<->B<->C (all via iBGP)

The goal is to allow A to announce routes to B, have B redistribute the route to C and have C announce it to the peers. 

The issue is that B receives the route (and adds it to the kernel) however it does not send it to C.

Any ideas how to fix this?
