Q60IP Connectivity

SIMULATION This lab item requires tasks to be completed on virtual devices. Refer to the topology and tasks. All physical cabling is already in place. Routers 2 and 3 cannot be accessed. Configure OSPF routing for the network and ensure that R1 joins Area 0 without using network statements. Task 1 - Configure OSPF on R1 with only the following process ID and router ID: - Use process ID 33. - Use the E0/1 IP address as the router ID. Task 2 - Configure R1 to form neighbor adjacencies with R2 and R3 without using an OSPF network statement. - Configure R1 to always become the DR for Area 0. - Save the configuration to NVRAM before proceeding. <AnswerReveal answer={" "} explanation={"OSPF can be enabled per interface with `ip ospf <process-id> area <area-id>`, which avoids OSPF `network` statements while advertising each connected subnet and forming the required adjacencies. The router ID is explicitly set to 10.0.22.1, R1’s E0/1 address. OSPF elects the router with the highest interface priority as DR on broadcast/NBMA segments; priority 255 is the maximum value, so configuring it on every R1 Area 0 interface makes R1 preferred for DR election. A new election may be required if an existing DR was already elected."} />

Right

OSPF can be set up in one of two ways ip ospf command under the interfaces network command under the config-router

you dont need the neighbor command since this is NOT a no-broadcast netowork
