[devang_etcom]

this command is showing you the status of neighbour ...it means in which state you have your neighbourship with your neighbour(in your case its 2way)...and also the role of the neighbour in you ospf network...

This means that neither this router nor the neighbor is a DR or BDR. On multiaccess media (like ethernet) The routers only form full adjacency with DRs or BDRs; with all other routers they stay in 2way state.

In your case the router you are executing is neither the DR nor BDR. Similarly the neighboring router is neither the DR or BDR. These two routers are just neighbors on a multiaccess segment.

By the way it is DROTHER and not DBROTHER.

If you see neighbors stuck in this state, this could means 2 things:

1st, its a normal state for 2 DRother routers on the same multiaccess medium (ethernet for instance),

or could be a problem: if you set "ip ospf priority 0" in all interfaces that share the same multiaccess, then all none of the routers would be allowd to be DR or BDR and they will be stuck in this state.

Hope this help,
