The Prisma SD-WAN ION 3000 can be installed in two different modes—in analytics or control mode with an existing router or in the control mode by replacing the router. By installing the ION with an existing router, you can physically insert the ION 3000 into a network, thereby reducing interruption and insertion planning to a minimum. Or you can install the ION 3000 to replace an existing router, especially in environments where routers are not already present or required.
