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).

1

Deploy two NSX Edge devices for North-South Routing. 

2

Disable the firewall of the NSX Edge devices, this is required for equal-cost multi-path (ECMP) to operate correctly.

3

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).

4

The NSX Edge devices need to establish a connection to each of it's 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.

5

Configure the universal distributed logical router (UDLR) to use dynamic routing in Region B.

6

Verify that the UDLR is successfully peering, and that BGP routing has been established.

7

Configure the universal distributed logical router (UDLR) to use static routes for routing to the management servers in Region B.
