Show AnswerHide Answer
Correct Answer: C
To establish multipoint GRE tunnels between hub router R6 and branch routers R1, R2, and R3, the configuration on R1 must include a network ID for the NHRP protocol, correct tunnel source interface, and appropriate NHRP mappings. Option C meets these requirements with the necessary commands: it sets the tunnel source interface to e0/0, specifies the GRE multipoint mode, includes the network ID, assigns the NHS address to 192.168.1.6, and correctly maps the IP addresses involved in the GRE tunnels.

Carl1999Option: C
Feb 5, 2022C is correct B doesn't have a network iD command.

Feb 15, 2022B is not wrong because of the missing network ID command, but because it uses e0/1 as tunnel source on R1 and it should be e0/0

Mar 28, 2024All DMVPN spoke/hub can have different network-id. network-id is locally significant. We set uo tunnels through mappings.

Jun 17, 2024To clarify: The network-id's can be different. But they must be initiated to start the nhrp protocol.
