OS10.5.3.2 introduces the multisite fabric interconnect. This feature enables SFS virtual networks to be stretched between separate SmartFabrics over traditional L3 networks. The SmartFabrics may be in the same data center, or in different sites. The SmartFabrics may be connected directly or through external switches.
The following figure shows a direct connection between SmartFabric leaf switches in two sites.
The following figure shows two SmartFabrics connected through an external network. The deployment in this guide uses this method.
