OSPF DR/BDR (Open Shortest Path First Designated Router/Backup Designated Router) is a mechanism in OSPF routing protocol where one router is elected as the Designated Router and another as the Backup Designated Router to reduce network traffic and enhance routing efficiency.
OSPF DRBDR Definition: OSPF DR/BDR (Open Shortest Path First Designated Router/Backup Designated Router) is a mechanism in OSPF routing protocol where one router is elected as the Designated Router and another as the Backup Designated Router to reduce network traffic and enhance routing efficiency.
OSPF DR/BDR refers to the two roles in an OSPF (Open Shortest Path First) network - Designated Router (DR) and Backup Designated Router (BDR). The DR is responsible for maintaining neighbor relationships and exchanging routing information with all routers in a broadcast network. The BDR serves as a standby to take over the DR role in case the DR fails. These roles reduce the number of adjacencies formed between routers, improving OSPF network efficiency and stability.
