SD-WAN

= SDWAN Lab = This section guides you to build your own SDWAN labs on a single Host Server like XenServer, VMWare, etc.

Running VM

 * Download CB VWAN 8.1 VPX XVA image file from download.citrix.com
 * You need atleast 4 GB RAM for a single VPX.
 * Configuration is done only on the Master Control Node (MCN).

Managing VM

 * Once VPX is Up and running, login into VPX console.
 * Type command 'management_ip', press enter.
 * Enter command 'set interface 10.107.88.84 255.255.255.224 10.107.88.65'
 * Now enter command 'apply'

Enabling VWAN
CB-VW GUI > Configuration > Appliance Settings > Administrator Interface > Miscellaneous tab > Switch Console
 * Login into WebUI
 * Upload & apply License
 * Now Enable MCN
 * Click on “Switch to Client Console” to enable MCN mode.

Configuring
Add Sites > Basic Settings > Interface Groups
 * Sites


 * Connections
 * Provisioning = Bandwidth settings

Deploying
Configuration > Virtual WAN > Enable/Disable/Purge Flows
 * Save Config
 * Export Config & select Change Management Inbox
 * In the Change management page, Upload the Virtual Upgrade firmware file (.tar.gz)
 * Select the exported Config file and select Verify.
 * Click next once the verification is successful.
 * Click Stage Appliances. Wait for it to complete.
 * Click Next & Select Activate.
 * Click Activate Staged now to activate the software on this CB.
 * Wait for 120s.
 * CLick Done. Enable VWAN on this page:
