1. A system, comprising:
one or more processors;
one or more computer-readable non-transitory storage media comprising instructions that, when executed by the one or more processors, cause one or more components of the system to perform operations comprising:
receiving, at a first provider backbone bridge (PBB) device, an Ethernet frame from a first edge router, the Ethernet frame configured for transmission to a second edge router via a Media Access Control security (MACsec) connection and comprising an Ether-type field;
performing, by the first PBB device, a lookup of the Ether-type field of the Ethernet frame to determine a match with one or more pre-defined values;
determining, by the first PBB device, that the Ether-type field of the Ethernet frame matches the one or more pre-defined values;
rewriting, by the first PBB device, the Ether-type field of the Ethernet frame to an open value, the open value operable to allow the Ethernet frame to be transmitted to a next hop device;
transmitting, by the first PBB device, the rewritten Ethernet frame to the next hop device; and
performing, by the next hop device, a lookup of the Ether-type field of the rewritten Ethernet frame to determine a next action.
