Christopher, Thank you very much. This config helps a lot. It seems that my configuration is almost the same to the one you sent me. I will have to check it in detail, I will get back to the list when i have news about it, Panos Kolyvas Network Operations Center University of Athens Greece. > > The following config is taken from a working Cisco to ERX link.
