A Tier-1 Gateway can span multiple ESXi and KVM hosts. A Distributed Router can provide local routing between different segments on a host. A DR also provides distributed east-west routing functionality across hosts.
Things to know about a T1:
- T1 uplinks to a T0 router
- T1 has down links to segments
- Owned and config by the tenant
- Doesn’t require or use dynamic protocols
- Doesn’t support ECMP & must connect to the T0 Gateway
- Offers default gateway services to local logical networks (East-West)
- Provides logical switch interconnection and separation
- Requires an NSX Edge node only if services are used
Step.1 – Create a new T1 Gateway
Networking>Tier-1 Gateways>Add Tier-1 Gateway
Provide a name (I recommend whatever the Gateway is supporting, I.E Non-Production QA) & click save
Ensure “All Static Routes” “All Connected Segments & Service Ports” are select.
Then Save, Then Close
As you can see deploying a new T1 is simple and easy unless you are trying to push services down. Remember in my previous article I showed how to edit a T1 and connect it to a T0 router. I know what you are about to ask, where are the segments? That will be covered in my next blog on creating segments and tying them to a T1.
