You can configure an overlay network using the SD-WAN Software-Defined Wide Area Network. SD-WAN is an application for applying SDN technology to WAN connections that connect enterprise networks across disparate geographical locations. orchestrator. For more information about overlay network segmentation and SD-WAN Wide Area Network. WAN is a telecommunications network or computer network that extends over a large geographical distance. orchestrator, see the following topics:
Prerequisites
Before you begin, ensure that your deployment topology meets the following conditions:
- Aruba Gateways are onboarded to and are managed by Aruba Central.
- Aruba Gateways are provisioned as part of and groups in Aruba Central.
- Access to Central FQDNs must be allowed for device communication when SD-WAN Orchestrator service is enabled for an Aruba Central account.
- Aruba Gateways are upgraded to ArubaOS 8.4.0.0-1.0.5.1 or later software version.
- The overlay IPsec Internet Protocol security. IPsec is a protocol suite for secure IP communications that authenticates and encrypts each IP packet in a communication session. tunnels are initiated by Branch Gateways and terminated on a VPNC or another Branch Gateway using NAT Network Address Translation. NAT is a method of remapping one IP address space into another by modifying network address information in Internet Protocol (IP) datagram packet headers while they are in transit across a traffic routing device. traversal, therefore ensure that UDP User Datagram Protocol. UDP is a part of the TCP/IP family of protocols used for data transfer. UDP is typically used for streaming media. UDP is a stateless protocol, which means it does not acknowledge that the packets being sent have been received. 4500 port is permitted.
Configuration Steps
The following configuration steps are required for tunnel and route orchestration on Aruba Gateways:
- Configuring Uplinks for Tunnel Orchestration
- Setting Data Center Preference
- Configuring Global Settings
- Enabling Group Orchestration
- Configuring Network Segments
- Associating an Overlay Network Segment
- Configuring Branch Aggregate Routes
- Aggregating Routes from VPNCs in the Data Center
- Redistribute overlay routes. For information on redistributing overlay routes, see Advertising Overlay Routes.
