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
