Cisco uses LISP to articulate programmability

"LISP hides addresses behind a gateway," says Paul Vinciguerra, president of Vinci Consulting. "For circuit redundancy, instead of running BGP on two links we can use multiple cable modems or broadband connections to increase out bandwidth and spread across multiple carriers. That's multihoming without BGP."

LISP also allows Vinci to establish a virtual IPv6 network to aid in the migration from IPv4 to IPv6 addresses.

"We can put an IPv6 address behind the gateway even when the carrier isn't IPv6," Vinciguerra says. "It's IPv4 from our gateways to our routers, but it's IPv6 end-to-end."

Cisco plans to include LISP in its Cisco ONE onePK programmable networking schematic for routers and switches running its IOS, IOS XR and NX OS operating systems. LISP could serve as both a northbound and southbound interface and control protocol between the database and management applications, Cisco officials say. It will also interact with the CiscoONE controller programming the routers and switches.

LISP is already shipping on Cisco's ISR and ASR 1000 customer premises routers. Company officials are targeting end of 2012 for inclusion on the ASR 9000 service provider edge router, and mid-2013 for Catalyst switches. Mid- to late-2013 will see it on Nexus 3000 and 5000 series switch hardware, they say.
