• No new transport provisioning required (Dark fiber, MPLS, etc)• Eliminate months of re-design effort • Significant operations and provisioning cost savings (no new protocols )
Solution: OTV – Establish DCI in 5 minutes!
Deploy over existing Network
4 configuration commands per site
No Re-design Required

LISP: Location Identity Separation Protocol
Internet
Device IPv4 or IPv6 address represents identity and
location
Today’s Internet BehaviorLoc/ID “overloaded” semantic
x.y.z.1 When the device moves, it gets a new IPv4 or IPv6 address for its new identity and
location
w.z.y.9
Device IPv4 or IPv6 address represents
identity only.
When the device moves, keeps its IPv4 or IPv6 address.
It has the same identity
LISP BehaviorLoc/ID “split”
Internet
a.b.c.1
e.f.g.7
Only the location changes
x.y.z.1
x.y.z.1
Its location is here!
