Cisco ACI Multi-Site Connectivity and Policy (MCP) is a unique feature that allows you to manage and connect multiple ACI fabrics as one. MCP also allows you to centrally manage and enforce consistent policy across all your ACI fabrics.
Multi-Site Connectivity
With Cisco ACI Multi-Site Connectivity, you can connect multiple ACI fabrics as one, allowing you to manage them as a single entity. You can also centrally provision and monitor applications, enforce consistent policy, and perform troubleshooting across all your ACI fabrics.
Multi-Site Connectivity is built on the foundation of the Cisco ACI Spine-Leaf architecture, which uses a centralized spine switch to connect a group of leaf switches. The Cisco ACI Multi-Site solution uses the same Spine-Leaf architecture, but with multiple spines that are interconnected using Cisco’s high-speed interconnect technology.
This architecture provides a number of benefits, including:
Simplified management: because the spines are interconnected, you can manage them as a single entity.
Improved performance: the high-speed interconnects allow traffic to be evenly distributed across the spines, providing improved performance.
Increased scalability: the architecture can be easily scaled by adding additional spines.
Multi-Site Policy
Cisco ACI Multi-Site Connectivity also allows you to centrally manage and enforce consistent policy across all your ACI fabrics. This is accomplished using a new feature called Multi-Site Policy.
Multi-Site Policy allows you to define policy once and have it automatically enforced across all your ACI fabrics. This eliminates the need to manually configure policy on each individual fabric, saving you time and ensuring that policy is consistently applied.
Multi-Site Policy is based on Cisco’s Application Policy Infrastructure Controller (APIC) Policy Model. This policy model is a declarative, intent-based approach to policy that allows you to specify what you want to accomplish, rather than how to do it.
The APIC Policy Model is composed of three main components:
Subjects: identify the entities that policy will be applied to, such as applications, users, or devices.
Conditions: specify the conditions that must be met in order for policy to be applied, such as location or time of day.
Actions: define the actions that should be taken when policy is triggered, such as allow or deny access.
Multi-Site Policy is a powerful new tool that allows you to centrally manage and enforce consistent policy across all your ACI fabrics. By simplifying policy management and ensuring that policy is consistently applied, Multi-Site Policy can help you save time and improve the security and compliance of your ACI deployment.
