Why each option
When deploying a Cisco ACI Multi-Site fabric with spine back-to-back direct links for Layer 2 extension, the maximum number of sites that can be connected is two.
Cisco ACI Multi-Site implementations that utilize direct spine back-to-back links to stretch Layer 2 between fabrics are architecturally limited to connecting a maximum of two independent ACI sites.
The direct spine back-to-back link for Layer 2 extension in ACI Multi-Site is explicitly limited to two sites, not three.
A direct spine back-to-back link deployment for Layer 2 extension in ACI Multi-Site supports only two sites, not four.
Connecting five sites using direct spine back-to-back links is not a supported configuration for Layer 2 extension in a Cisco ACI Multi-Site fabric.
Concept tested: ACI Multi-Site L2 extension; Spine back-to-back limits
