Abstract: Various systems and methods for performing bit indexed explicit replication (BIER) using multiprotocol label switching (MPLS). For example, one method involves receiving a packet that includes a MPLS label. The packet also includes a multicast forwarding entry. The method also involves determining, based on the value of the MPLS label, whether to use the multicast forwarding entry to forward the packet. The method further includes forwarding the packet.

Abstract: In one embodiment, a method includes receiving at a first network device in a first virtual private network, a packet destined for a second network device in communication with a second virtual private network, and transmitting the packet over the second network, wherein the packet is encapsulated for transmittal on a tunnel extending from the first network device to the second network device. The first network device is in communication with a system operable to map and encapsulate the packet and provide an overlay that traverses over the second virtual private network. An apparatus and logic are also disclosed herein.

Abstract: Systems and methods are described for maintaining communication between hosts that, due to the roaming of a host, are no longer in the same LAN segment within a network. In one embodiment, the method includes receiving an address resolution request from the first host, the address resolution request requesting an actual media access control (MAC) address associated with an internet protocol (IP) address of the second host, obtaining the actual MAC address of the second host, the second host having roamed from away from a first network location where a first host is located, receiving a data packet from the first host that is to be delivered to the second host, and routing the data packet to the second host at its current location, the current location of the second host being determined by its actual MAC address.
