Citrix SD-WAN

Multi-region deployment

An SD-WAN appliance configured as Master Control Node (MCN) supports multi-region deployment. The MCN manages multiple Regional Control Nodes (RCNs). Each RCN, in turn, manages multiple client sites. The MCN can also be used to manage some of the client sites directly.

With MCN as the control node of the network and RCNs as the control nodes of the regions, SD-WAN can manage up to 6000 sites.

Multi-region deployment enables you to fragment a network into regions and set up a tiered network; such as branch (client) > RCN > MCN.

An MCN with a single region can be configured with a maximum of 1000 sites. You can keep the existing sites in the default region and add new regions with RCNs and their sites for multi-region deployment.

For more information about Multi-region deployment through Citrix SD-WAN Orchestrator service, see Regions.
