QuestionQ4

Tunnels

Your GRE tunnel is not changing to the Up status.

What should be the first troubleshooting step?

  • A Verify tunnel endpoint reachability.
  • B Verify that the status of the management interface is up.
  • C Verify the status of the management routing instance.
  • D Verify that the routing instance for GRE tunnels is created.
Explanation

GRE tunnel establishment depends on IP reachability between the tunnel source and destination endpoints. Confirming that the tunnel endpoints can reach each other is the first diagnostic step.
