An inter-site policy manager, named Cisco ACI Multi-Site, is used to manage the different fabrics and to define inter-site policies. Complementary with Cisco APIC, in Multi-Site each site is an availability zone (APIC cluster domain), which can be configured to be a shared or isolated change-control zone. The Multi-Site solution enables extending the policy domain end-to-end across fabrics. You can create policies in the Multi-Site GUI and push them to all sites or selected sites. Alternatively, you can import tenants and their policies from a single site and deploy them on other sites. Multi-Site enables a global view of site health. From the GUI of the Multi-Site Policy Manager, you can launch site APICs.
