Abstract:
Methods and systems for hardware-accelerated packet multicasting are provided. According to one embodiment, a first packet to be multicast to a first destination and a second packet to be multicast to a second destination are received. The first and second packets are classified in accordance with different virtual routers (VRs) of multiple VRs instantiated by a virtual routing engine (VRE) of a virtual routing system by determining a first selected VR to multicast the first packet and a second selected VR to multicast the second packet. For each of the first and second packets: a routing context of the VRE is switched to a routing context associated with the selected VR; at least a portion of the packet is read from one of multiple multicast address spaces associated with the selected VR; and the packet is forwarded to the destination.
