LISP overview

What is LISP ? It's Locator/ID Separation Protocol from Cisco system. This a new mechanism which will change the size of routing table inside router. First, the core router will not care EID anymore. By doing this, ingress and egress router acts the key point in LISP. Howevr the MR, MS proxy also import.

The encap could be a big performance impact of the service. The first probe packet in the flow might be missing on the way to dest ip. And the multi-vendor support still not get answer from others(Juniper, 3com, etc)

From the LISP, we can see that CSCO put a new way on next generation routing table , but JNPR still make a big machine put everything bigger and bigger(memory, CPU, Disk).
