LISP provides a streamlined solution for handling multi-provider internet connectivity and policy without BGP configuration complexity. Its benefits include load-balancing ingress traffic across different providers. It has simple policy management. There is no need for any new appliances, is supported on most Cisco IOS and Cisco IOS/XR devices it can be downloaded from CCO.
Rider IT staff spent countless hours of research, late nights coordinating with the support staff of both ISP’s, and routinely adjusting complex Border Gateway Protocol (BGP) policies. Despite the best efforts of all involved, they were simply unable to achieve the goal of two well balanced Internet links. Essentially, this resulted in the University paying for bandwidth that wasn’t even being used, and slowness at the Internet edge that seemingly could only be alleviated by “throwing more money” at the problem by purchasing more bandwidth on the saturated link.
In late 2011, they began to hear rumblings about Cisco’s Locator/ ID Separation Protocol (LISP), and there was a growing excitement among the NJEdge.net staff with regard to success they experienced using LISP in their own test, and eventually production, environments.
After being contacted by James Stankiewicz, Director of Internet engineering at NJEDge.Net, Rider decided to take the leap and deploy LISP at the edge in early 2012
Working closely with Mr. Stankiewicz, and Cisco support engineers, Rider shut down BGP protocol on the University’s edge router, and made the change to LISP with just a few lines of code. The entire process took only a few minutes, but the results were noticeable almost immediately. In a matter of hours, bandwidth data collected from the router was demonstrating that Rider was now getting diverse and balanced traffic across two Internet links. Even more important, was a noticeable improvement in performance.
Considering the move to LISP having been a huge success, Rider University is now beginning to explore using the protocol within its internal infrastructure, and is looking forward to the other benefits that LISP can provided with respect to security and disaster recovery.
