MPLS label stripping does not participate in the MPLS control-plane, and MPLS does not have a next protocol indicator.

Impact

GRE/MPLS packets with IPv6 traffic encapsulated are not forwarded to the egress VLAN.

Conditions

This is encountered when attempting to pass IPv6 packets to GRE-encapsulated MPLS on BIG-IP systems.
