Which statement is true about GRE encapsulation?
GRE (Generic Routing Encapsulation) encapsulates the entire original packet, which includes both the IP header and the IP payload. The encapsulated packet then receives a new outer IP header for routing to the tunnel endpoint.
Correct Answer is C As a packet enters an IP tunnel, the tunneling protocol encapsulates the entire packet, including the header
Agreed C - GRE encapsulates the entire packet and then adds and outer IP header to the tunnel endpoint
