The IKEv2 Mobility and Multihoming (MOBIKE) protocol is an extension
of the Internet Key Exchange Protocol version 2 (IKEv2).  These
extensions should enable an efficient management of IKE and IPsec
Security Associations when a host possesses multiple IP addresses
and/or where IP addresses of an IPsec host change over time (for
example, due to mobility).
