SYSTEMS AND METHODS FOR AN EXTRANET MULTICAST VIRTUAL PRIVATE NETWORK IN A VIRTUAL ROUTING AND FOWARDING BASED CUSTOMER EDGE DEVICE
First Claim
1. A network device operating as a customer edge device, the network device comprising:
- one or more processors in communication with the plurality of interfaces and a memory;
a plurality of forwarding tables stored in the memory; and
a plurality of virtual routing and forwarding (VRF) instances, each of the plurality of VRF instances being associated with one of the plurality of forwarding tables, the plurality of VRF instances including subscribing VRF instances and a default VRF instance, wherein a multicast stream received on the default VRF instance is replicated by the one or more processors and transmitted to each of the subscribing VRF instances.

Abstract
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.

15. A method for providing a multicast stream transmitted from a provider edge device to a customer edge device, the method comprising:
-
receiving the multicast stream at the provider edge device; transmitting a single copy of the multicast stream from the provider edge device to the customer edge device; receiving the single copy of the multicast stream on a default virtual routing and forwarding (VRF) instance; and replicating the single copy of the multicast stream on the customer edge device to provide a replicated copy to each of a plurality of subscribing VRF instances. - View Dependent Claims (16, 17, 18, 19, 20)
