Controling BGP Route Propagation in Transit Gateway

0

When setting up a VPN connection to Transit Gateway, is there way to control which routes are propagated across the VPN tunnel via BGP?. Currently, any new attachments to the Transit Gateway will propagate the subnets across the VPN tunnels. How can a user control which IP ranges are propagated and how can they only propagate certain custom ranges?

The way to control route propagation over BGP for VPN is with TGW route tables. Users can create a new TGW route table just for the VPN tunnel(s) and then only propagate the routes that are needed.
