Abstract
Systems and methods are provided herein for an efficient method of tunneling that enables a network to transition from one address family to another address family with a reduction in traffic loss. This may be accomplished by updating network devices to support a second address family in addition to a first address family. Once the second address family is supported by the network devices, tunnel endpoints using those network devices can establish a second tunnel based on the second address family. As the second tunnel is established, the network continues to use a first tunnel to route network traffic while the first tunnel uses the first address family.
