Issue with Static Route

I'm encountering a challenge in my NSX Manager environment when it comes to the propagation of static routes to Tier-1 Gateways. I have configured a static route at the Tier-0 Gateway level, but it doesn't seem to be applied automatically to the associated Tier-1 Gateway. As a result, traffic appears to be dropped, and I have to allow it manually.

Could someone please guide me on the proper configuration steps to ensure that static routes defined at the Tier-0 level are propagated and applied to Tier-1 Gateways seamlessly? Additionally, are there any specific troubleshooting steps I should follow to identify and resolve this issue?

Any insights or recommendations would be greatly appreciated.

Please check if your static routes for redistribution is checked under BGP

It appears that you are mixing up routes and firewall policies here. Adding a route will not create a firewall policy for that traffic. If you see traffic being dropped by the firewall, you'll have to create a policy. If you're unsure if the firewall is the cause, Traceflow might help you out.

Additionally, as far as I know, T0 do not distribute anything down to T1's as the T0 is the default route for all T1's attached to it. A T1 can propagate it's own local routes and networks towards the T0.

this does not solve the problem, the rules are redistributed, but they drop automatically. We already have the configuration you wrote
