Well, that does make sense, now that you mention it. (OSPF sending multicast Hellos on a serial interface). OSPF uses Hellos as a keepalive, not just for establishing adjacencies.
Notice, that your reply is still hard to read because we can't tell what you wrote and what I wrote. But if you're reading and writing e-mail from a Web page, I could see how that could happen. It's not a big deal. Thanks for the reply. Priscilla At 09:15 PM 1/14/02, s vermill wrote: >Good question. The IBM 6611 does bridging for one thing.
