DR and BDR selection Lab

 #ospf #protocol #configuration #lab #DR #BDR Lab objectives: Ensure router R1 is the DR for network 100.1.1.0 /24. Ensure router R3 is the BDR for network 100.1.1.0 /24. Ensure router R5 is the DR for network 100.1.2.0 /24. without changing the priority Ensure router R2 is the BDR for network 100.1.2.0 /24. You are not allowed to change the priority. Solution configurations: R1: conf t int fa 0/0 ip address 100.1.1.2 255.255.255.0 no shutdown exit router ospf 10 network 100.1.1.0 0.0.0.255 area 0 network 100.1.2.0 0.0.0.255 area 0 log-adjacency-changes conf t router ospf 10 log-adjacency-changes exit exit R2: the solution to achieve all objectives: change priority of R1 must be higher than R3 change priority of R2 must be lower than R1 change router-id manually to higher router ID 120.120.120.2
