Hello, This follow-up is to thank you all who replied and mention the solution (what is good for the history). I forced binding to the correct IP address declaring neighbor's local address, and added a static route to the box, instead of using the default one, although they were nexthoping to the same address. Finally I removed the "passive" keyword. Now its OK with the first BGP neighbor, I will setup the second tomorrow morning but probably there wont be any other problem. Thank you all and thanks for OpenBGP. Way simple, functional and much better/clearer than cisco. -- =========== Eduardo Meyer
