Question

SIMULATION 75 Please use the "Tasks" and "Topology" tabs to complete this lablet. Topology Configure OSPF routing for the network by completing the following tasks: Task 1 Configure OSPF on R2. Ensure R1 and R3 become neighbors. ● Use process ID 30. ● Use 10.22.22.22 as the router ID. ● Under the OSPF process, advertise the following specific prefixes: - 10.0.23.0/28 - 10.0.12.0/30 Task 2 Ensure R2 always becomes the DR. Answer: - R2 OSPF configuration (process 30, router-id, and only the two required prefixes in area 0): conf t router ospf 30 router-id 10.22.22.22 network 10.0.23.0 0.0.0.15 area 0 network 10.0.12.0 0.0.0.3 area 0 - Ensure R2 always becomes the DR (set highest OSPF interface priority on the multiaccess/broadcast segments): interface e0/0 ip ospf priority 255 interface e0/1 ip ospf priority 255 - If a DR/BDR already exists, force a new election after changing priority (one of these): clear ip ospf process (or) shut/no shut the OSPF-enabled interfaces on the segment
