You want to ensure traffic is routed through a GRE tunnel. In this scenario, which two statements will satisfy this requirement? (Choose two.)

The correct answer is A. Tunnel endpoints must have a route that directs traffic into the tunnel. B. All intermediary devices must have a route to the tunnel endpoints. Option A is correct. For traffic to be sent through a GRE tunnel, there must be a route that directs the traffic into the tunnel.

Question

You want to ensure traffic is routed through a GRE tunnel. In this scenario, which two statements will satisfy this requirement? (Choose two.)

Options

  • ATunnel endpoints must have a route that directs traffic into the tunnel.
  • BAll intermediary devices must have a route to the tunnel endpoints.
  • CKeepalives must be used on stateless tunneling protocols.
  • DBFD must be used on the stateless tunneling protocols.

Explanation

Option A is correct. For traffic to be sent through a GRE tunnel, there must be a route that directs the traffic into the tunnel. This is typically accomplished through the use of a static route or a dynamic routing protocol. Option B is correct. All intermediary devices must have a route to the tunnel endpoints. In real- world scenarios, the tunnel endpoints for a tunnel going over the Internet must have globally reachable internet addresses. Otherwise, intermediate routers in the Internet cannot forward the tunneled packets.
