Does this mean Neighbour ? and also do ospf routers form direct adjacencies with each other ? even without the DR/BDR or is this needed for them to see each other ?
Adjacency means neighbor relationship. On a broadcast multiaccess network like ethernet, OSPF routers donot form adjacencies directly with each other, they form it with DR and BDR only.
Yes, Only with the DR and BDR.The DR and BDR functaionality is to limit the number of adjancies that can be formed in an area thus reducing the OSPF convergence due to one neighor failure or a link failure.
Can you please tell me the steps that it goes through when finding an adjacency ? I always thought it would see directly the neighbour and add it to the routing table ?
So if the DR and BR go off, the network would be uselesss, and so do all routers form no kind of direct neighbourship so to speak ?
