Number of T0 Configuration limitation

Hi Folks,

I just wanted to double confirm if the number of T0 deployable limitation is up to 80 per System/NSX Manager or per Edge.

With vCD for muli-tenant services , limitation 80 x T0s per system is too smsall.

That is why I am posting this so all you guys comments would be highly appreciated.

NSX-T Data Center 2.4.1 Configuration Maximums

Layer 3 Networking (Logical Routing)

  Tier 0 Logical Routers 80

  Tier 1 Logical Routers 2,000

Thanks for your attentions.

The documentation is correct. Since you can only have one T0 per edge:

"An Edge node can support only one tier-0 gateway or logical router."

Tier-0 Gateways

If you need more scale than you will need more NSX instances.

Thanks for your input but the documents of NSX previous versions 2.3 or ealier NOT latest 2.4 says:

"An NSX Edge cluster can back multiple tier-0 logical routers. Tier-0 routers support the BGP dynamic routing protocol and ECMP."

Tier-0 Logical Router

That is very weird and is it the degraded feature?

The statements are actually different. You can have only 1 Tier-0 per edge, and this is confirmed on page 49 of the Reference Design guide that came before 2.4 and is available on https://communities.vmware.com/docs/DOC-37591 Since Edge Clusters are made of multiple Edge Nodes you can have multiple Tier-0 routers on them, just not more than 1 on each individual edge.
