About Transit Gateway Cloud Service Provider Settings

This section describes the cloud service provider settings for a Transit Gateway.

Summarize CIDR(s) to AWS TGW

Enable this setting to limit routes propagated to TGW to only three RFC 1918 CIDRs and specific non-RFC 1918 CIDRs. Limiting routes saves route propagation time.

Leave this setting disabled (the default setting) to maintain better segmentation behavior without improving performance.

AWS TGW Edge Segmentation

AWS TGW Edge Segmentation allows you to further specify on each AWS TGW Aviatrix _Edge_Domain connection which domain the Transit Gateway can communicate with.

This feature is not available for Transit Gateways that have FireNet added, or have Network Segmentation enabled.

After you turn On this option you can build domain connection policies to specify which Network Domain this AWS TGW Aviatrix_Edge_Domain connection can communicate with.

For more information see the topic "Configuring AWS TGW Edge Segmentation".
