An engineer is implementing the Cisco ACI fabric and wants to reduce the amount of TCAM resources consumed by the fabric. The engineer also needs to ensure that all EPGs m a VRF consume the same…

Configuring a single contract provided and consumed in all EPGs without vzAny would still require individual EPG-to-EPG relationships, potentially consuming more TCAM resources than using vzAny.

Preferred groups in a VRF allow EPGs within the group to communicate freely, but they do not address the requirement of ensuring all EPGs consume the same services through a specific contract, nor do they primarily focus on TCAM reduction for contract rules.

Implementing an unenforced VRF means no contracts are applied, allowing free communication, but this fails the requirement to define and enforce specific services for EPGs within that VRF.

The vzAny feature in Cisco ACI allows all EPGs within a VRF to implicitly consume a common set of services defined by a single contract associated with vzAny. This significantly reduces TCAM entries by aggregating contract rules across multiple EPGs to a single vzAny object, ensuring consistent service consumption while optimizing hardware resources.
