What is the purpose of the generic routing encapsulation tunneling protocol?

  • to provide fixed flow-control mechanisms with IP tunneling between remote sites
  • to support basic unencrypted IP tunneling using multivendor routers between remote sites
  • to manage the transportation of IP multicast and multiprotocol traffic between remote sites
  • to provide packet level encryption of IP traffic between remote sites

Explanation: The GRE tunneling protocol is Cisco proprietary and does not include any flow-control mechanisms by default. GRE does not support encryption and is used to manage the transportation of IP multicast and multiprotocol traffic.
