Cisco Application Centric Infrastructure Multi-Site Lab v3

April 2020

The Data Center Practice is pleased to announce that Cisco Application Centric Infrastructure Multi-Site Lab v3 is available on dCloud to Customer, Partner and Cisco users in US East, US West, APJ and EMEA dCloud locations.

As the newest advance in the Cisco ACI methods to interconnect networks, Cisco ACI Multi-Site is an architectural approach for interconnecting and managing multiple sites, each serving as a single fabric and availability zone. As shown in the diagram, the Multi-Site architecture has three main functional components:

  • Two or more ACI fabrics built with Nexus 9000 switches deployed as leaf and spine nodes.
  • One APIC cluster domain in each fabric.
  • An inter-site policy manager, named Cisco ACI Multi-Site, which is used to manage the different fabrics and to define inter-site policies.

Multi-Site has the following benefits:

  • 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.
  • MP-BGP EVPN is used as the control plane between sites, with data-plane VXLAN encapsulation across sites.
  • 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.
  • Cross-site namespace normalization is performed by the connecting spine switches. This function requires Cisco Nexus 9000 Series switches with EX on the end of the name, or newer.
  • Disaster recovery scenarios offering IP mobility across sites is one of the typical Multi-Site use cases.
