AWS Transit Gateway Connect today increased the default service quotas for the dynamic routes advertised to and from a Transit Gateway Connect peer. You can now advertise up to 1,000 dynamic routes (an increase from 100) from a customer gateway appliance in an on-premises network or a virtual router appliance in a VPC to a Transit Gateway Connect peer. Similarly, you can now advertise up to 5,000 routes (an increase from 1,000) from a Transit Gateway Connect peer to a customer gateway appliance or a virtual router appliance. Advertised routes come from the route table that's associated with the AWS Transit Gateway Connect attachment.
The new limits apply in all regions where AWS Transit Gateway Connect is available. The higher limits are reflected in your account automatically and you do not have to take any action. For more information, please see the AWS Transit Gateway quotas documentation.
