The method includes detecting a loss of connection at an incoming interface to an upstream neighbor of the network node, where the network node is in a multicast communication network that includes a multicast tree to provide connectivity from a common source node to one or more multicast recipient nodes. The multicast communication network further includes a set of one or more secondary paths to provide redundancy to the multicast tree, and sending a notification packet downstream toward the one or more multicast recipient nodes when the network node cannot re-route the multicast data traffic to allow the multicast data traffic to be received by the multicast recipient nodes, wherein the notification packet causes one or more downstream nodes to switch multicast reception to one or more of the set of one or more secondary paths to re-route the multicast data traffic."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Enhancements to PIM fast re-route with upstream activation packets","description":"A method performed by a network node.
