LISP
There are several advantages to decoupling Location and Identifier, and to LISP specifically.
- Improved routing scalability
- BGP-free multihoming in active-active configuration
- Address family traversal: IPv4 over IPv4, IPv4 over IPv6, IPv6 over IPv6, IPv6 over IPv4
- Inbound traffic engineering
- Mobility
- Simple deployability
- No host changes are needed
- Customer driven VPN provisioning replacing MPLS-VPN
- Network virtualization
- Customer operated encrypted VPN based on LISP/GETVPN replacing IPsec scalability problems
- High availability for seamless communication sessions through (constraint-based) multihoming

“Taught me my alphabet to say,
To lisp my very earliest word,”
