Prerequisites for an NSX Edge Cluster
Before you deploy an NSX Edge cluster you should review the
prerequisites.
- Verify that separate VLANs and subnets are available for the NSX host overlay VLAN and NSX Edge overlay VLAN. You cannot use DHCP for the NSX Edge overlay VLAN.
- Verify that the NSX host overlay VLAN and NSX Edge overlay VLAN are routed to each other.
- For dynamic routing, set up two Border Gateway Protocol (BGP) peers on Top of Rack (ToR) switches with an interface IP, BGP autonomous system number (ASN), and BGP password.
- Reserve a BGP ASN to use for the NSX Edge cluster’s Tier-0 gateway.
- Verify that DNS entries for the NSX Edge nodes are populated in the customer-managed DNS server.
- The vSphere cluster hosting an NSX Edge cluster must include hosts with identical management, uplink, NSX Edge overlay TEP, and NSX Edge overlay TEP networks (L2 uniform).
- The management network and management network gateway for the NSX Edge nodes must be reachable from the NSX host overlay and NSX Edge overlay VLANs.

Cloud Foundation
4.5 and later support deploying an NSX Edge
cluster on a vSphere cluster that is stretched. Edge nodes are placed on ESXi hosts in
the first availability zone (AZ1) during NSX Edge cluster deployment.
