Three-Segment VXLAN can be configured to enable communication between VMs in different DCs.
To meet the requirements of geographical redundancy, inter-regional operations, and user access, an increasing number of enterprises are deploying data centers (DCs) across multiple regions. Data Center Interconnect (DCI) is a solution that enables intercommunication between the VMs of multiple DCs. Using technologies such as VXLAN and BGP EVPN, DCI securely and reliably transmits DC packets over carrier networks. Three-segment VXLAN can be configured to enable communications between VMs in different DCs.
