Abstract:
1. A method, comprising: establishing a virtual trunk link between a first network element and a second network element, wherein the first and second network elements are located at a first site, wherein the first site and a second site comprise at least a portion of an overlay network; receiving data traffic at the first network element, wherein the data traffic is associated with a segment of the overlay network; mapping a first network identifier allocated to the overlay network segment at the first network element to a virtual trunk link and a VLAN ID; forwarding the data traffic from the first network element to the second network element via the virtual trunk link with the VLAN ID; and sending a pruning data packet for signaling segment interests for the first site, wherein a payload of the pruning data packet comprises an opcode for performing at least one of querying for segment interests of another site, for joining a segment, and for leaving a segment.
