Provide steps to clear the stale routes so the SDDC Group shows the correct routes on the External TGW.
Symptoms:
Routes were added/removed on an External TGW (Customer Managed TGW) and they are not showing under the Route Table for the SDDC Group. Stale routes are being seen from the previous static routes on the External TGW, and the newly added routes may not be showing up in the SDDC Group.
All routes are showing correct in the AWS Console for the External TGW, but the VMC SDDC Group is showing incorrect routes.
