1. A method of collecting telemetry in a multicast network having a first branch and a second branch, each branch comprising a plurality of sequential nodes, the plurality of sequential nodes including an initial branch node and a destination device, the method comprising:
injecting a synthetic telemetry packet into the multicast network at the initial branch node of the first branch;
the initial branch node transmitting the synthetic telemetry packet to a next sequential node of the first branch, wherein each sequential node transmits the synthetic telemetry packet to a next sequential node in the first branch until the synthetic telemetry packet reaches the destination device of the first branch;
the initial branch node of the first branch replicating the synthetic telemetry packet and transmitting the replicated synthetic telemetry packet to the initial branch node of the second branch; and
the initial branch node of the second branch transmitting the replicated synthetic packet to a next sequential node of the second branch, wherein each sequential node of the second branch transmits the synthetic telemetry packet to a next sequential node in the second branch until the synthetic telemetry packet reaches the destination device of the second branch;
wherein the synthetic packet defines which nodes of the plurality of sequential nodes are to collect telemetry, parameters for collecting telemetry and instructions for transmitting collected telemetry.
