Pub/Sub is the focus area for LISP innovation moving forward, so immediately you'll receive: Dynamic Default Border, faster overlay traffic convergence, and the ability to configure Extranet Policy if required. In future as more features are added to LISP Pub/Sub you'll be able to access those features. LISP/BGP will need to be migrated to LISP Pub/Sub later, and eventually (long time frame) LISP/BGP will be retired. Regards, Jerome

Hello Jedolphi,

what is configuration required at fusion to deploy LISP PUB/SUB

Hi, Fusion device configuration remains 99% the same for either LISP/BGP or LISP Pub/Sub Fabric Sites. One maybe small difference for some customers: a Pub/Sub External Border Node must have a default route in RIB, and usually this default route is learned from the Fusion device. Regards, Jerome
