This chapter provides a step-by-step example for setting up HA (high availability) Silver Peak appliances by using Web Cache Communications Protocol (WCCP) service with a Cisco router. If one appliance goes down, the other then handles all the traffic. In an Active/Active deployment, the peered appliances are also load balancing.
In this example, Site A deploys two active, redundant appliances (named
A1 and
A2) out-of-path (Router mode) and, remotely,
Site B deploys a single appliance (named
B), in-line (Bridge mode). The focus of this chapter is on the HA appliances; in practice, the remote appliance can be in either bridge or router mode.
