Deploy over existing Network 4 configuration commands per site No Re-design Required Ethernet Overlay One Logical Data Center Automatic Fault Isolation

  • LISP: Location Identity Separation Protocol Internet Device IPv4 or IPv6 address represents identity and location Today’s Internet Behavior Loc/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 Behavior Loc/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!
