Support for high-availability ethernet protocols in overlay networks

A network device operating as a source tunnel endpoint, comprising:

• a processing resource;
• and
• a non-transitory machine-readable storage medium comprising instructions executable by the processing resource to:
• determine whether a received packet is a Parallel Redundancy Protocol (PRP) packet;
• in response to determining that the received packet is not a PRP packet, apply Equal-Cost Multi-Path (ECMP)-based load balancing and forward the received packet to an ECMP next-hop network device toward a destination tunnel endpoint;
• and
• in response to determining that the received packet is a PRP packet, forward the received packet to a predetermined next-hop network device toward the destination tunnel endpoint.

A non-transitory computer-readable storage medium storing instructions to:

• determine, at a network device operating as a source tunnel endpoint, whether a received packet is a Parallel Redundancy Protocol (PRP) packet;
• in response to determining that the received packet is not a PRP packet, apply Equal-Cost Multi-Path (ECMP)-based load balancing and forward the received packet to an ECMP next-hop network device toward a destination tunnel endpoint;
• and
• in response to determining that the received packet is a PRP packet, forward the received packet to a predetermined next-hop network device toward the destination tunnel endpoint.
