Tier-0 Gateways

A tier-0 gateway performs the functions of a tier-0 logical router. It processes traffic between the logical and physical networks.

NSX Cloud Note: If using NSX Cloud, see How to use NSX-T Data Center Features with the Public Cloud for a list of auto-generated logical entities, supported features, and configurations required for NSX Cloud.

An Edge node can support only one tier-0 gateway or logical router. When you create a tier-0 gateway or logical router, make sure you do not create more tier-0 gateways or logical routers than the number of Edge nodes in the NSX Edge cluster.

Note: When connecting tier-0 uplinks to multi-chassis port-channel topologies such as vPC (virtual PortChannel) or VSS (Virtual Switching System) from Cisco, or MLAG (Multi-Chassis Link Aggregation) from Arista, be sure to consult with the network provider to understand the limitations of the topology when it is being used for transit routing.
