Figures 10.71 and 10.72 show the IS-IS neighbor tables of two routers, router A and router B, connected to a Token Ring network. IS-IS is exchanging routes between the two routers and entering them into the route tables, but no IP traffic is passing between the routers. What is wrong?

Figure 10.73 shows debug messages from a router that is not establishing an adjacency with a neighbor on its interfaces TO0. What is wrong?
