Silver Peak SD-WAN Deployment Guide
NOTE: Router modeOut-of-path deployment, where data traffic is redirected by using policy-based routing (PBR), Web Cache Coordination Protocol (WCCP), or Virtual Router Redundancy Protocol (VRRP). is suggested for out-of-pathSame as Router mode. In an out-of-path deployment, policy-based routing (PBR), VRRP, or WCCP redirects the traffic to the Silver Peak appliance for processing. deployments such as PBRPolicy-based routing is a technique used to make routing decisions based on policies set by the network administrator. and WCCPWeb Cache Communications Protocol. A Cisco-developed content-routing protocol that provides a mechanism to redirect traffic flows in real-time. It has built-in load balancing, scaling, fault tolerance, and service-assurance (failsafe) mechanisms. Utilizes HIA (Here I Am) messages from SP devices and ISY (I See You) messages to the router. until these limitations are fixed or when the topology is not susceptible to creating a loop.
