I've been stuck on this task for the entire day despite following the instructions in the workbook. I don't know what is causing the problem. I have configured the interface of each device in the correct area but I am having lots of problems in establishing the adjacency between the OSPF neighbors. Some of the states are DOWN, some say INIT and some say EXSTART. I changed the Router-id on SW3 and R3 to 150.1.9.9 and 150.1.3.3 respectively as suggested in the workbook but still my adjacencies are not coming up. Any help will be welcome.
