Ethernet virtual private network attachment circuit aware virtual local area network bundle service

Abstract:

Techniques for routing traffic across different virtual local area networks (VLANs) within a single bridge domain are described. One technique includes receiving at a first network device a packet from a second network device on a first interface of multiple interfaces within a bridge domain at the first network device. Attachment circuit information associated with the packet is determined. An information element that includes an indication of the attachment circuit information is generated. The information element is transmitted to the third network device.
