Good question. The IBM 6611 does bridging for one thing. The other hint was that it was attempting to send an OSPF Hello on a serial interface. Does OSPF do that? How does it establish adjacency to a neighbor router on a WAN? On a point-to-point network, I figured it just knew who its neighbor was.
On a non-broadcast, multiple-access network, such as Frame Relay, you normally configured the neighbor command. I've only seen the OSPF multicast Hellos on LANs, (but I can't afford a WAN Sniffer anymore! ;-) Gurus? Help? Thanks. Priscilla Priscilla, I was fairly certain that OSPF exchanges hellos on serial interfaces. I turned on OSPF on a router in my lab and then turned on debug ip packet. In deed, hellos with a destination address of 224.0.0.5 are going out all interfaces - including serial. P.S. Anyone seeing this may be confused because you didn't include the original message. PLEASE, people, reply with the body of the message in the reply. We work in connectionless, stateless mode. How do you expect anyone to easily connect this to the discussion about a router failing to forward a packet on a PPP link to an IBM 6611. Hello????? I am fairly new around here. It appears that a lot of folks participate in this forum via a list. I have been doing so via the web page, so I am not familiar with what the rest of you see. Did I do it right this time?
