This feature will allow the user to select whether port mirror destinations of type GRE tunnel include the optional “key” field in the GRE header on certain platforms. The key field allows the user to uniquely identify a particular packet flow. The feature also allows the user to specify the value of the 32 bit key field. The format of the key field within the GRE header can be seen in RFC 1701 - Generic Routing Encapsulation (GRE).

MPLS-over-GRE encapsulation support in EOS 4.17.0 enables tunneling IPv4 packets over MPLS over GRE tunnels. This feature leverages next-hop group support in EOS. With this feature, IPv4 routes may be resolved via MPLS-over-GRE next-hop group to be able to push one MPLS label and then GRE encapsulate the resulting labelled IPv4 packet before sending out of the egress interface.

This feature terminates GRE packets on a TapAgg switch by stripping the GRE header and then letting the decapped packets go through the normal TapAgg path. With this feature, we can use an L3 GRE tunnel to transit tapped traffic to the TapAgg switch over an L3 network. That would widely extend the available use cases for TapAgg.
