This design uses two separate NSX instances per region. One instance is tied to the Management vCenter Server, and the other instance is tied to the Compute vCenter Server. Deploy and configure the NSX instance for the management cluster in Region B.
Prerequisites for Implementation of the Management NSX Instance in Region B Before you deploy the NSX Components of the Management Cluster in Region B, verify that your environment satisfies the requirements for this deployment.
Deploy the NSX Manager for the Management Cluster NSX Instance in Region B For every NSX Manager instance there is one connected vCenter Server. Deploy the NSX Manager virtual appliance and connect it to the vCenter Server.
Join the Management NSX Manager to the Primary NSX Instance in Region B Join the secondary NSX instance to the respective primary instance.
Prepare the ESXi Hosts in the Management Cluster for NSX in Region B NSX kernel modules packaged in VIB files run within the hypervisor kernel and provide services such as distributed routing, distributed firewall, and VXLAN bridging capabilities. To use NSX, you must install the NSX kernel modules on the ESXi hosts.
Configure the NSX Logical Network for the Management Cluster in Region B After all the deployment tasks are completed, you configure the NSX logical network.
Update the Host Profile for the Management Cluster in Region B After you configure NSX logical networking on the hosts, update the host profile of the management cluster and remediate the hosts to align their configuration.
Deploy the Platform Services Controllers Load Balancer in Region B Configure load balancing for all services and components related to Platform Services Controllers (PSC) using an NSX Edge load balancer.
Configure NSX Dynamic Routing in the Management Cluster in Region B NSX for vSphere creates a network virtualization layer on top of which all virtual networks are created. This layer is an abstraction between the physical and virtual networks. You configure NSX dynamic routing within the management cluster, deploying two NSX Edge devices and configure a Universal Distributed Logical Router (UDLR).
Update Distributed Firewall for Region B After deploying the vCenter Server you must add it to the distributed firewall exclusion list.
Test the Management Cluster NSX Configuration in Region B Test the configuration of the NSX logical network using a ping test. A ping test checks if two hosts in a network can reach each other.
Test the Management Clusters Routing Failover After the clusters are fully configured in Region A and Region B, you verify that the network connectivity between the regions works as expected.
Deploy Application Virtual Networks in Region B Deploy the application virtual networks for the region.
Deploy the NSX Load Balancer in Region B Deploy a load balancer for use by management applications connected to the application virtual network Mgmt-xRegion01-VXLAN.
