There's a very subtle difference here. Neighbourships will send hello messages and process received hello messages. Adjacencies go further than neighbours, by sharing information through LSA …

show adjacency show ip cef adjacency And that's where I noticed something interesting — "incomplete adjacency." What was happening was that the router knew the route (from the routing table), but it …

Two OSPF routers can form adjacency over different OSPF Process ID's. You can run multiple OSPF processes on a router, using the Process ID as a distinguisher. You can have two backbone areas …

DR OTHER routers can indeed form OSPF adjacency but only with DR and BDR.

Here my inputs regarding your comment. 1. No sudden drops on the utilization during the flap of PIM adjacency. 2. I forgot to add that this logs on SW1 is reoccurring, not just minute but more than an …
