What is considered a requirement for passing traffic through GRE tunnels?
A requirement for passing traffic through GRE tunnels is that tunnel endpoints must have a route that directs traffic into the tunnel. This routing enables the proper encapsulation and forwarding of packets through the tunnel, ensuring that data can travel from one endpoint to the other. Without a route directing traffic into the tunnel, the data packets would not be correctly forwarded through the GRE tunnel.
I guess there is the mistake written in C You must be able to reach the remote endpoint through the INTERNET. not tunnel. D variant i like more. bc if dont have any route through that tunnel. how it can pass ? Im more for D. but C is able (if Internet is used).
The answer is D, the tunnel endpoints need a route for the traffic in the tunnel with next hop as the tunnel inteface (gr././. or ip././.).
