NSX-T supports a multi-tiered routing between provider router and tenant routing function. The top-tier logical router is referred to as tier-0 while the bottom-tier logical router is tier-1.
This structure gives both provider and tenant administrators complete control over their services and policies.
There is no dynamic routing between tier-1 and tier-0 LRs. The NSX-T platform takes care of the auto-plumbing between LRs at different tiers. The following list details route types on tier-1:
Static – Static routes configured by user via NSX-T Manager.
NSX Connected – Directly connected LIF interfaces on the LR. 172.16.10.0/24 and 172.16.20.0/24 are NSX Connected routes for the tier-1 LR.
Tier-1 NAT – NAT IP addresses owned by the tier-1 LR discovered from NAT rules configured on the tier-1 LR. These are advertised to the tier-0 LR as /32 routes.
Follow the steps below to create T1 Gateway.
1 – Select Networking > Tier 1 Gateways > ADD TIER-1 GATEWAY.
