A method can be used to route a communication within a network. The method can include receiving a first communication at a first edge router, wherein the first communication is a Layer 2 communication. The method can also include determining that the first communication has a destination that includes a first multicast group and a second multicast group different from the first multicast group. The method can also include encapsulating the first communication within a second communication, wherein the second communication is a Layer 3 communication, and wherein the second communication is a single communication. The method can further include sending the second communication towards the first multicast group and the second multicast group. A system can be configured to carry out the method.
