It is time to deploy a Stretched Tier-0 Gateway
- Configure segments for the Tier-0 Uplink
- Create a Stretched Tier-0 GW
- Connect the Stretched Tier-1 GW to the Stretched Tier-0 GW
- Test end to end connectivity
First we need to log into the Primary Global Manager
Networking > Conenectivity > Segments
ADD SEGMENT
Name the Segment – I recommend putting something to indicate stretched uplink
Choose the primary location and the primary VLAN Transport Zone
Provide the VLAN ID and save
No
Confirm the status is successful
Create a second segment for the other uplink
Provide a name that indicates this is a VLAN from the secondary site and that it is for stretching
Select your secondary location and the VLAN Transport Zone for your second site
Provide the VLAN ID
Save
No
Confirm the status is success
Networking > Connectivity > Tier-0 Gateways
ADD TIER-0 GAEWAY
Enter a name for this gateway
HA Mode set to Active Active
Pick the primary location and the edge cluster that has the RTEP
ADD LOCATION
Disable Mark all locations as Primary
Enter in your secondary location and RTEP Cluster
Set Mode to Secondary
Failback Preferences to Priority 1
SAVE
Yes
Set
ADD Interface
Provide a name to indicate this interface belongs to the primary site
Select the primary location
Provide the IP address for the uplink
Connect to the primary location T0-uplink segment
Then select the edge node that supports the RTEP
Save
Confirm the status successful
ADD INTERFACE
Repeat the process for the second uplink to the secondary location
Confirm both uplinks are up
Change the local AS to whatever is in your environment
Click Set under BGP Neighbors
ADD BGP NEIGHBOR
Enter the IP for the neighbor
Select your primary site LM
Enter the remote AS number
Put in the remote IP
Save
ADD BGP NEIGHBOR
Repeat process but for your secondary site
Confirm status is successful
Click Set for the primary location
ADD ROUTE RE-DISTRIBUTION
Provide a name
Click Set
Select Static Routes and Connected Interfaces & Segments for both Tier-0 and Tier-1
Apply
Repeat for secondary site too
Confirm Route Re-Distribution is set for both locations
Save
Close Editing
Confirm the status is successful
Edit your stretched T1
Add the stretched T0 GW to the stretched T1 GW
Confirm the status
Finally we need to test connectivity from an outside workstation to the test virtual machines in your Primary and Secondary locations
This proves the ability to ping from outside the NSX-T network to virtual machines inside the NSX-T network
