But since you configured 10.200.206.249/30 on the interface, you should already be able to reach 10.200.206.250, since the kernel will create the route 10.200.206.248/30 through the tunnel. This could be the source of your issue, since (IIRC) Bird sometimes has trouble with peers that are reachable with a /32 route. If removing the /32 route doesn't work, maybe adding a "protocol device" and "protocol direct" would solve the issue. Baptiste
