To support the communication between tenant workloads by using application virtual networks in NSX-T and to connect tenant workloads to the external network, configure dynamic routing in the shared edge and compute cluster.
Routing occurs in both the North-South and East-West directions.
North-South traffic leaving or entering the workload domain, for example, a virtual machine on an overlay network communicating with an end-user device on the corporate network.
East-West traffic remains in the workload domain, for example, two virtual machines on the same or different segments communicating with each other.
Create an NSX-T Edge Cluster Profile For availability of the routing services and connectivity to the external network, you create a multi-node cluster of NSX-T Edge nodes. To define a common configuration for both NSX-T Edge nodes, you create an edge cluster profile.
Deploy the NSX-T Edge Appliances To provide tenant workloads with routing services and connectivity to networks that are external to the workload domain, deploy two NSX-T Edge nodes.
Join the NSX-T Edge Nodes to the Management Plane After you deploy the NSX-T Edge appliances in the shared edge and compute cluster, to connect them to the NSX-T Manager cluster, join them to the management plane.
Create an Anti-Affinity Rule for the NSX-T Edge Nodes in the Shared Edge and Compute Cluster To ensure that the two NSX-Т Edge appliances run on different ESXi hosts, create a DRS VM-host anti-affinity rule. If a failure occurs on one of the hosts, the appliance on the other host continues providing routing services.
Add the NSX-T Edge Nodes to the Transport Zones After you deploy the NSX-T Edge nodes and join them to the management plane, to connect the nodes to the workload domain, add them to the transport zones for uplink and overlay traffic, and configure the N-VDS switches on each edge node.
Create an NSX-T Edge Cluster Adding multiple NSX-T Edge nodes to a cluster increases the availability of networking services. An NSX-T Edge cluster is necessary to support the Tier-0 and Tier-1 gateways in the workload domain.
Create and Configure the Tier-0 Gateway The Tier-0 gateway in the NSX-T Edge cluster provides a gateway service between the logical and physical network. The NSX-T Edge cluster can back multiple Tier-0 gateways.
Create and Configure the Tier-1 Gateway Create and configure the Tier-1 gateway to re-distribute routes to the Tier-0 gateway and to provide routing between tenant workloads.
Verify BGP Peering and Route Redistribution The Tier-0 gateway must establish a connection to each of the upstream Layer 3 devices before BGP updates can be exchanged. Verify that the NSX-T Edge nodes are successfully peering and that BGP routing is established.
