SD-Access LISP

LISP

Locater Identifier Separation Protocol

Usually an IP includes two things:

• Identity
• Location

LISP allows these to be de-coupled.

In LISP these are called namespaces.

EID

Endpoint Identifier

This is the ID portion

RLOC

Routing Locator

This is where the device is.

EID-to-RLOC

The table used to map where a identity currently is.

For wireless it could be roaming to a new AP.

VRFs

The LISP instance ID is the VRF.
