This feature introduces the hardware forwarding support for IPv4 over IPv4, GRE-Tunnel interfaces on Arista Switches. A GRE-Tunnel interface acts as a logical interface which performs the GRE encapsulation or decapsulation. IPv6 payload over IPv4 GRE-Tunnel interfaces is supported with limitations (see Limitation section).

This feature allows encapsulating (and decapsulating) L2 traffic from a given interface or subinterface over a GRE tunnel. An MPLS label is added to identify the ingress interface (similar to MPLS pseudowires) and the GRE tunnel is used to transport the packets to a remote endpoint.
