Hi Luca,
Too be honest, I haven't attempted routing over Asynch in years. But I did
look up a valid config that we've used in the past. I only have the remote
router config, not the 2600. And it was running EIGRP over the line, not
OSPF. Besides from this, I can only offer to try different variations if
possible (apply IP to the remote router, different routing protocol,
etc...).
HTH,
Sean
