摘要:
The techniques described are directed to providing mass withdrawal of media access control (MAC) routes for network devices in an Ethernet virtual private network data center interconnect (EVPN DCI). MAC routes to reach the learned MAC addresses are stored in routing tables with corresponding top-of-rack Ethernet segment identifier (TOR-ESI) values that represent the Ethernet segments from where the MAC addresses were learned. A provider edge (PE) network device may configure and advertise a virtual Ethernet segment identifier (vESI) that includes a plurality of TOR-ESI values. As Ethernet segments of the data center become unavailable, the corresponding TOR-ESI values may be withdrawn from the vESI to form an updated vESI. In this way, MAC routes having a TOR-ESI value that was withdrawn from the vESI may be removed from the routing tables in each of the network devices.
