Abstract: In general, techniques are described for performing a mass withdrawal of media access control (MAC) addresses using a reduced number of route withdrawal messages within a singly-homed segment of an Ethernet Virtual Private Network (EVPN). The techniques may include determining a segment identifier of the segment and sending a route advertisement to advertise a route for the segment identifier to a provider edge network device. The techniques may include sending a route advertisement to advertise one or more media access control (MAC) routes for the layer two segment. The techniques may also include, responsive to determining a link failure between a first provider edge network device and a customer edge network device, sending a withdrawal message to the second provider edge network device for the route associated with the segment identifier to withdraw all of the plurality of MAC routes at the second provider edge network device.
