[HECnet] Need help with DECnet routing

I do have "Hello timer = 15" on DUSTY. I do have connectivity between LULU and DUSTY, but now I wonder whether it's full connectivity. Perhaps there's a problem with Personal Alpha's network emulation. It may not be receiving all of the packets. What does node LULU indicate as the adjacency? It should be node DUSTY unless you have another Level 1 (with higher priority) or Level 2 router on the same circuit. When I do a "SHOW CIRC SVA-0 STAT" on LULU, I don't see any adjacent node. --Marc . Must be some problem with either of the nodes then, because normally the adjacency will come up, when the end node starts receiving the router hellos. Can you monitor the Ethernet with a protocol analyzer? You should see the hellos from both nodes. One more thing to check: you might have some equipment filtering multicast packets on the Ehternet. Like e.g. a routing switch. Also firewalls (software in a PC) might do that. I assume you run the Personal Alpha on a PC.
