L2 LISP for Data Center Mobility

L2 LISP (Layer 2 Locator/Identifier Separation Protocol) is primarily utilized for enhancing seamless mobility within data center environments. One of the critical advantages of deploying L2 LISP is its ability to allow workloads to migrate across the data center without necessitating changes to their IP or MAC addresses. This feature is particularly beneficial in scenarios involving virtual machines (VMs) or containers that need to move across data centers for purposes such as load balancing, maintenance, or disaster recovery.

In the context of retaining the same MAC address, L2 LISP provides a significant benefit. While physical hosts have hard-wired MAC addresses, virtual hosts, such as VMs, have MAC addresses that can be reconfigured. L2 LISP enables the movement of virtual entities across data center infrastructure without altering their MAC addresses, which simplifies network management and enhances flexibility.
