Source routed multicast LSP
Abstract:
Source routed multicast LSP is described herein. In one embodiment, when a first node receives a first packet having a label stack including a plurality of labels compatible with MPLS (multi-protocol label switching), in response to a first label on a top of the label stack, the first packet is duplicated into a second packet. In addition, at least two labels are popped from the top of the label stack of the second packet forming a third packet. Thereafter, the first and third packets are processed based on a label on the top of the label stack of the first and third packets respectively. Other methods and apparatuses are also described.
