routeTableIds

(Multi-AZ only) Specifies the route tables in which Amazon FSx creates the rules for routing traffic to the correct file server. You should specify all virtual private cloud (VPC) route tables associated with the subnets in which your clients are located. By default, Amazon FSx selects your VPC's default route table.

Amazon FSx manages these route tables for Multi-AZ file systems using tag-based authentication. These route tables are tagged with Key: AmazonFSx; Value: ManagedByAmazonFSx. When creating FSx for ONTAP Multi-AZ file systems using CloudFormation we recommend that you add the Key: AmazonFSx; Value: ManagedByAmazonFSx tag manually.
