Systems and methods for an extranet multicast virtual private network in a virtual routing and forwarding based customer edge device

摘要

An information handling system is provided. The information handling system includes a customer edge device coupled to a provider edge device. The customer edge device provides a default virtual routing and forwarding (VRF) instance that receives a multicast stream from the provider edge device. The information handling system also includes a plurality of host devices and a plurality of virtual local area networks (VLANs). Each of the VLANs includes at least one of the host devices and is assigned to a subscribing VRF instance, with each of the subscribing VRF instances subscribing to the default VRF instance in order to receive a copy of the multicast stream from the provider edge device. The single copy of the multicast stream is transmitted over the PE-CE link regardless of the number of subscribing VRFs.

1. A network device operating as a customer edge device, the network device comprising:
one or more processors that are in communication with a plurality of host device interfaces that are each configured to couple to at least one host device, a provider edge device interface that is configured to couple to a provider edge device, and a memory; and a plurality of forwarding tables stored in the memory; wherein the one or more processors are configured to provide a plurality of virtual routing and forwarding (VRF) instances that are each of associated with a respective one of the plurality of forwarding tables and that include a respective subscribing VRF instances associated with each of the plurality of host device interfaces and a default VRF instance associated with the provider edge device interface, wherein the default VRF instance is configured to receive a single multicast stream from a provider device through the provider edge device interface, replicated the single multicast stream to provide a plurality of replicated multicast streams, and transmit one of the plurality of replicated multicast streams to each respective subscribing VRF instances to provide that replicated multicast stream to the at least one host device coupled to the host device interface associated with that respective subscribing VRF instance.
