Abstract:
A network device may generate a route advertisement that includes a media access control (MAC) address. The MAC address may correspond to a data link established between the network device and a customer edge (CE) device. The network device and the CE device may be associated with an Ethernet virtual private network (EVPN) that includes other network devices that are remote from the CE device. The network device may cause the route advertisement to be outputted over the EVPN. The route advertisement may permit the other network devices to learn that the data link is directly reachable via the MAC address, and may permit the other network devices, when configured as maintenance endpoints (MEPs), to directly address performance monitoring-related unicast packets, intended for the data link, using the MAC address, such that flooding of the performance monitoring-related unicast packets is avoided.

Claim (Index 1):
A method, comprising:\n providing, by a first provider edge (PE) device, a route advertisement,\n the first PE device being part of an Ethernet virtual private network (EVPN), and being multihomed to by a first customer edge (CE) device, \n a first attachment circuit being established between the first PE device and the first CE device, \n the route advertisement including a media access control (MAC) address, corresponding to the first attachment circuit, that is utilized as a connectivity fault management (CFM) MAC address for a maintenance endpoint (MEP) configured on the first attachment circuit; \n receiving, by a second PE device, the route advertisement,\n the second PE device being part of the EVPN, and being communicatively coupled to a second CE device, \n a second attachment circuit being established between the second PE device and the second CE device, \n the second PE device being configured to monitor connectivity between the second PE device and the second CE device and the first PE device and the first CE device; and \n causing, by the second PE device and by monitoring the connectivity, traffic to be directed to the first PE device and/or to the first attachment circuit based on the route advertisement,\n the traffic not being provided to any other PE device, on the EVPN, that is multihomed to by the first CE device.
