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 consolidated cluster, deploying two NSX Edge devices and configure a Universal Distributed Logical Router (UDLR).
Create a Logical Switch for use as the Transit Network for Consolidated SDDC Create a Logical Switch for use as the transit network.
Deploy NSX Edge Devices for North-South Routing for Consolidated SDDC
Disable the Firewall Service in ECMP Edges for Consolidated SDDC Disable the firewall of the NSX Edge devices. This is required for equal-cost multi-path (ECMP) to operate correctly.
Enable and Configure BGP Routing for Consolidated SDDC The Border Gateway Protocol (BGP) is a protocol for exchanging routing information between gateway hosts (each with its own router) in a network of autonomous systems (AS).
Verify Peering of Upstream Switches and Establishment of BGP for Consolidated SDDC The NSX Edge devices need to establish a connection to each of the upstream BGP switches before BGP updates can be exchanged. Verify that the NSX Edges devices are successfully peering, and that BGP routing has been established.
Deploy the Universal Distributed Logical Router for Consolidated SDDC Deploy the Universal distributed logical router (UDLR).
Configure Universal Distributed Logical Router for Dynamic Routing for Consolidated SDDC Configure the Universal distributed logical router (UDLR) to use dynamic routing in management and workload consolidation.
Verify Establishment of BGP for the Universal Distributed Logical Router for Consolidated SDDC Verify that the UDLR is successfully peering, and that BGP routing has been established.
