Silver Peak SD-WAN Deployment Guide

Server Mode Deployments

Server modeDefault mode of a virtual appliance. Out of path, single port (mgmt0), one IP address. is the default for virtual appliances and:

• Only uses the mgmt0 interface for management and datapath traffic.
• Uses one IPInternet Protocol. Network layer protocol in the TCP/IP stack that enables a connectionless internetwork service. address.
• Requires traffic redirection.
• Can only be deployed 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..

Unlike other Out-of-Path deployments, this mode requires the hosts to configure a route or gatewayAlso called protocol converters, can operate at any layer of the OSI model. The job of a gateway is much more complex than that of a router or switch. Typically, a gateway must convert one protocol stack into another. to the Silver Peak appliance IPInternet Protocol. Network layer protocol in the TCP/IP stack that enables a connectionless internetwork service. address to redirect traffic to the Silver Peak.

Traffic redirected to the Silver Peak is optimized and placed in a tunnelEncapsulating one type of network protocol (called the payload protocol) within a different delivery protocol. A logical connection between two devices, in our case, two Silver Peak appliances.. This includes:

• Traffic arriving in a tunnelEncapsulating one type of network protocol (called the payload protocol) within a different delivery protocol. A logical connection between two devices, in our case, two Silver Peak appliances. from another Silver Peak
• Any non-tunnelized traffic that needs to be directed to the local appliance, such as optimized traffic that has not yet been tunnelizedEncapsulating one type of network protocol (called the payload protocol) within a different delivery protocol.
