Similarly, how do you know if a doctor is BDR?
Two rules are used to elect a DR and BDR:
- router with the highest OSPF priority will become a DR. By default, all routers have a priority of 1.
- if there is a tie, a router with the highest router ID wins the election.
Also Know, what happens in Exstart state? In the exstart state, the router sends a unicast packet to the neighbor to elect master and slave. This is true unless you have a point-to-point link, in which case it sends a multicast packet.
Also to know, why do we need DR and BDR?
When multiple OSPF routers are connected to a multi-access medium such as Ethernet, a Designated Router (DR) and a Backup Designated Router (BDR) are elected. DR’s reduce network traffic as only they maintain the complete ospf database and then send updates to the other routers on the shared network segment.
What is the purpose of DR and BDR in OSPF?
DR/BDR Roles Within OSPF, the role of the Designated Router (DR) and a Backup Designated Router (BDR) is to act as a central point for exchanging of OSPF information between multiple routers on the same, multiaccess broadcast network segment.
