As discussed in Chapter 4, "Design Fundamentals," some definite benefits are to be gained by selecting the router within the network that should be the designated router (DR) as well as the backup designated router (BDR). Here, you want to choose a specific router to be the DR by manually assigning the priority of a router and thus affecting the DR election process. Recall that the election process first compares priority (default of 1), where the highest value wins (in the case of a tie, the highest RID wins). If the priority is set to 0, the router is ineligible to become the DR:
