Citrix SD-WAN


SD-WAN site communicating with non SD-WAN site over eBGP:

When a site without SD-WAN appliance is communicating with another site with SD-WAN appliance (Site-A) over a single WAN path (only internet is available), and if the site with SD-WAN appliance (Site-A) loses internet connectivity, then the site without SD-WAN can communicate with Site-A through another SD-WAN appliance site (Site-B). Site-B funnels traffic from the site without SD-WAN appliance to the Site-A.

Communication between SD-WAN sites using Virtual Path and eBGP:

Provides underlay route learning to communicate with remote site local subnets when the virtual path is down between two sites while the Virtual WAN appliance is still up and running.
