Generic UDP Encapsulation (GUE) is a general method for encapsulating packets of arbitrary IP protocols within a UDP tunnel. GUE provides an extensible header format with optional data. In this release, decap capability of GUE packets of variant 1 header format has been added. This variant allows direct encapsulation using the UDP header without the GUE header. The inner payload could be one of IPv4, IPv6, or MPLS.

Generic UDP Encapsulation (GUE) is a general method for encapsulating packets of arbitrary IP protocols within a UDP tunnel. While GUE supports an extensible header format with optional data, currently we only support the variant 1 header format, which directly encapsulates the IPv4/IPv6 payload without a GUE header.
