Silver Peak SD-WAN Deployment Guide

Deployment Modes

The versatility of OrchestratorFormerly GMS. Silver Peak global management software. Manages, provisions, and monitors Silver Peak devices within a network. enables you to configure your deployment in various modes:

• Router - Can be in-line or 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. and uses multiple ports. Best for complex networks.
  • Do you want your traffic to be in-path or 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.? This mode supports both deployments. In-path deployment offers much simpler configuration.
  • Does your router support VRRPVirtual Router Redundancy Protocol is a standard redundancy protocol designed to increase the availability of servicing hosts on the same subnet., 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., or PBRPolicy-based routing is a technique used to make routing decisions based on policies set by the network administrator.? If so, you may want to consider 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. 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). deployment. You can set up more complex configurations, which offer load balancingA technique to spread work between two or more computers, network links, CPUs, hard drives, or other resources, in order to get optimal resource utilization, maximize throughput, and minimize response time. Using multiple components with load balancing, instead of a single component, may increase reliability through redundancy. The balancing service is usually provided by a dedicated program or hardware device. between appliances and high availability.
  • If your LANLocal Area Network. destination is behind a router or L3 switchA network device that filters and forwards frames based on the destination address of each frame. The switch operates at Layer-2 (data link layer) of the Open System Interconnection (OSI) model., you need to add a LANLocal Area Network.-side route (a LANLocal Area Network. next-hop).
• Bridge - Can only be in-line and uses 2 or 4 ports. Easiest setup for simple networks.
  • Do you have a physical appliance or a virtual appliance?
  • A virtual appliance has no fail-to-wire, so you need a redundant network path to maintain connectivity if the appliance fails.
  • If your LANLocal Area Network. destination is behind a router or L3 switchA network device that filters and forwards frames based on the destination address of each frame. The switch operates at Layer-2 (data link layer) of the Open System Interconnection (OSI) model., you need to add a LANLocal Area Network.-side route (a LANLocal Area Network. next-hop).
  • If the appliance is on a VLANVirtual Local Area Network. A means by which LAN users on different physical LAN segments are afforded priority access privileges across the LAN backbone so that they appear to be on the same physical segment of an enterprise-level logical LAN. trunk, then you need to configure VLANs on the Silver Peak so that the appliance can tag traffic with the appropriate VLAN tagSee 802.1q encapsulation.
• Server - Can only be 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. and uses 1 port (mgmt0). Best for backup configurations.
