LISP host mobility use cases

Locator Identity Separation Protocol (LISP) allows hosts to move from one site to another while maintaining the same assigned IP addresses. There are two fundamental ways in which this can be configured:

  • LISP Host Mobility with an Extended Subnet - This option involves physically extending the subnet to a different site using OTV, VPLS, or other LAN extension technologies. In this way, when a host moves, it can maintain the same IP address within the same subnet, thus the problem of changing IP addresses is eliminated.
  • LISP Host Mobility Across Subnets - This solution allows a host to be migrated to a remote IP subnet while retaining its original IP address using a mapping mechanism.
