Methods, tools, and a multicast connectivity architecture are provided for provisioning bundled high bandwidth multi-channel multimedia broadcast services over a packet switched communications network. Multicast group membership join/prune requests generated by the destination network nodes are processed on edge. Multicast tree connectivity in the core of the communications network is static and centrally provisioned based on multicast group member edge network nodes associated with subscribers, while dynamic multicasting techniques are employed over the distribution portion of the service provider's communications network to deliver requested content to each destination network node. The methods and tools compute multicast trees, configure on-tree branching network nodes, and establish Virtual Private LAN network overlays for channel bundles to convey multi-channel content in the core of the managed communications network between edge network nodes. Centralized multicast tree provisioning enables the use of efficient multicast tree topologies, while VPLS packet transport provides interoperability between disparate Layer-2 packet transport technologies employed in different portions of the communications network.
