Abstract
Embodiments herein describe using translation mappings and security contracts to establish interconnects and policies between switching fabrics at different sites to create a unified fabric. In one embodiment, a multi-site controller can stretch endpoint groups (EPGs) between the sites so that a host or application in a first site can communicate with a host or application in a second site which is assigned to the same stretched EPG, despite the two sites have different namespaces. Further, the shadow EPGs can be formed to facilitate security contracts between EPGs in different sites. Each site can store namespace translation mapping that enable the site to convert namespace information in packets received from a different site into its own namespace values. As a result, independent bridging and routing segments in the various sites can be interconnected as well as providing application accessibility across different fabrics with independent and private namespaces.
