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).
Deploy NSX Edge Devices for North-South Routing in Region B You deploy two NSX Edge devices for North-South Routing.
Disable the Firewall Service in Region B Disable the firewall of the NSX Edge devices. This is required for equal-cost multi-path (ECMP) to operate correctly. Perform this procedure for each NSX Edge device.
Enable and Configure Routing in Region B Enable the Border Gateway Protocol (BGP) to exchange routing information between the NSX Edge services gateways in a network of autonomous systems (AS).
Verify Peering of Upstream Switches and Establishment of BGP in Region B The NSX Edge devices must establish a connection to each of its upstream BGP switches before BGP updates can be exchanged. Verify that the NSX Edge devices are successfully peering and that BGP routing has been established.
Configure Universal Distributed Logical Router for Dynamic Routing in Region B Configure the universal distributed logical router (UDLR) to use dynamic routing in Region B.
Verify Establishment of BGP for the Universal Distributed Logical Router in Region B Verify that the UDLR is successfully peering and BGP routing has been established.
Configure Static Routes on the Universal Distributed Logical Router in Region B Configure the universal distributed logical router (UDLR) to use static routes for routing to the management servers in Region B.
