The present disclosure describes methods and systems for enabling a migration of network elements from a first location to a second location remote from the first location without changing the Internet Protocol (IP) addresses, subnet mask, and/or default gateway of the network elements. The first location has a first Locator/Identifier Separation Protocol (LISP) router configured on a stick and the second location having a second LISP router configured on a stick. Both the first LISP router and the second LISP router are on the same subnet. Effectively, LISP provides a Layer 3 extension stretching a subnet across the first location and the second location (Stretched Subnet Mode (SSM)). By implementing LISP routers in this manner, system engineers can migrate network elements easily between two locations.
