ABSTRACT:
A network device seamlessly handles multicast traffic flow between virtual private networks (VPNs) and content providers located external to the VPNs. For example, the network device, such as a router, comprises an interface card and a forwarding component. The forwarding component maintains forwarding data for a public network and forwarding data for the virtual private network. The interface card receives a multicast packet from a virtual private network destined for a multicast content provider external to the virtual private network. When forwarding the multicast packet, the forwarding component bypasses the forwarding data for the public network and forwards the multicast packet to the multicast content provider in accordance with the forwarding data for the public network.
