Regarding above diagram, routers on a single phase undergo a series of claims in advance of building a successful adjacency. The fresh new neighbors and you will DR election are performed via the Good morning process. Of course a beneficial router notices alone inside the the next door neighbor’s Hello packet, the official transitions to help you “2-Way”. At that point DR and you may BDR election is performed on the multi-supply avenues. An excellent router continues creating a keen adjacency that have a next-door neighbor when the possibly of the two routers is good DR otherwise BDR
