The ability to have multiple vlans configured within one link between two switches, this allows for easy management of separate networks without having many individual ports or devices needed at each location where you need access from your central office /mainframe/etc etc.. We use it primarily as an interconnecting layer but we also are able utilize some features such as MPLS capabilities which can be used when not needed just because they're there if desired - great tool! Nothing really I dislike about dispersible edge so far though maybe its all my fault (no pun intended) since i haven't ran into any issues yet with using them specifically? It's been super simple thusfar no problems whatsover!! Great product overall would highly recommend trying out their services before deciding against purchasing other products like cisco has done over time especially considering how much easier managing these types of environments become when working towards.
