Abstract
Techniques are described for providing robust control plane asserts in a network using Protocol Independent Multicast (PIM) or other routing protocols for controlling delivery of multicast traffic. In one example, a router includes a control unit having a hardware-based processor executing a Protocol Independent Multicast (PIM) protocol. The control unit, when executing the PIM protocol, initiates an election process for selecting, from a plurality of routers, a forwarding router to forward multicast traffic to a shared media computer network. In addition, the control unit determines whether the multicast traffic has been received by the router and outputs, in association with the election process, a PIM assert message that includes an indication as to whether the router has successfully received the multicast traffic.
