Bidirectional multicasting over virtual port channel
First Claim
1. A computer-implemented method for transporting bidirectional multicast traffic over a virtual port channel (VPC), comprising:
- determining a first set of metrics for a first VPC switch;
determining a second set of metrics for a second VPC switch;
sending the first set of metrics from the first VPC switch to the second VPC switch;
receiving, at the first VPC switch, the second set of metrics for the second VPC switch; and
determining, at the first VPC switch, whether to instantiate a designated forwarder (DF) operation based on the first set of metrics and the received second set of metrics indicating the first VPC switch provides a more efficient network route to a rendezvous point (RP) than the second VPC switch;
receiving, at the second VPC switch, the first set of metrics for the second VPC switch; and
determining, at the second VPC switch, whether to instantiate a designated forwarder (DF) operation based on the received first set of metrics and the second set of metrics indicating the second VPC switch provides a more efficient network route to a rendezvous point (RP) than the first VPC switch;
wherein the first and second VPC switches self-determine whether or not they will be a direct forwarder.

Abstract
Aspects of the subject technology relate to systems for arbitrating direct forwarder (“DF”) instantiation between VPC peers used to facilitating the transport of bidirectional multicast traffic over a L2/L3 network boundary. In some aspects, arbitration of DF instantiation on a given VPC peer can include determining a first set of metrics for a first VPC switch, determining a second set of metrics for a second VPC switch, and determining, at the first VPC switch, whether to instantiate a designated forwarder (DF) operation based on a comparison of the first set of metrics and the second set of metrics. Methods and machine-readable media are also provided.
