An engineer working for a private telecommunication company with an employee id 4298 53 420 must evaluate connectivity to the new data centre location based on Cisco Nexus 7000 Series Switches. The IP

IS-IS multi-site over ACI is a routing protocol combined with a data center fabric, which does not primarily focus on Layer 2 extension between geographically dispersed data centers over an arbitrary IP transport.

VXLAN over EoMPLS combines two different tunneling technologies; EoMPLS is for point-to-point Layer 2 extension over MPLS, and VXLAN is for Layer 2 overlay over IP, making this combination not directly applicable for optimized Layer 2 extension over any IP transport.

BGP over VPLS is primarily a Layer 2 VPN technology using MPLS as the underlying transport, not typically designed for optimized Layer 2 extension over a generic IP underlay with OTV-specific traffic localization features.
