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: In one embodiment, a device receives a payload encapsulated in an Internet Protocol (IP) transport header having a time-to-live (TTL) value, and decapsulates the payload while maintaining the TTL value. In response to determining that a destination of the payload is not attached to the device, the device may then re-encapsulate the payload in a new IP transport header with a new TTL value that is less than the maintained TTL value, and transmits the re-encapsulated payload toward the destination. In this manner, loops in overlay networks may be prevented based on eventual expiration of the TTL value of the IP transport header, accordingly.
