OSPF Adjacency process is stuck on 'Loading' for a neighbor on one Virtual Router. Other neighbors on the same Virtual Router or other Neighbors on other Virtual Routers using the same link are on 'Full' state. If the OSPF process is restarted the adjacency process gets to 'Full' state for the problematic neighbor

Okay, when I started my CCNA, I had the same question. I guess a lot of people are confused about this. Lets start with a simple analogy. Lets say you live in an apartment. An OSPF adjacency is established in several steps. In the first step, routers that intend to establish full OSPF neighbor adjacency exchange OSPF Hello packets. Both OSPF neighbors are in the Down state, the initial state of a neighbor conversation that indicates that no Hello’s have been heard from the neighbor. OSPFv2 multiarea adjacency allows you to configure a link on the primary interface in multiple OSPF areas to enable optimized routing. The following commands were introduced or modified: ip ospf multi-area , ip ospf multi-area cost , and show ip ospf multi-area . OSPF routers transition through several phases before they establish a neighbor adjacency. The routers exchange different types of packets during these phases. This exchange of messages allows all routers that establish an adjacency to have a consistent view of the network.

Which OSPF component is identical in all routers in an OSPF area after convergence? adjacency database link-state database* routing table SPF tree 3. Which OPSF packet contains the different types of link-state advertisements? hello DBD LSR LSU* LSAck 4. What happens The OSPF adjacency formed and link state databases were synchronized. The output of show ip ospf neighbor (S-Series) respectively show ospf neighbor (EXOS) showed full adjacencies, but the X460-G2 did not learn any routes over OSPF (the output of show iproute origin ospf did not contain any routes). OSPF Adjacency OSPF Adjacency States. Routers establish OSPF adjacency to use OSPF. From the beginning of the establishment to the full adjacency, there are some states. These states are mentioned below:
