Extending a VPC into AWS Wavelength

When extending a VPC from a parent region into AWS Wavelength Zones, many of the considerations seen with AWS Outposts and AWS Local Zones remain the same.

Communication between AWS Wavelength Zones

Just as with AWS Outposts and AWS Local Zones, it is not possible to route traffic from one zone to another via the parent region within the same VPC. As shown in the next diagram, multiple VPCs must be configured, and a mechanism such as AWS Transit Gateway should be used to route between them within the parent region:

It is, however, possible for resources in one zone to talk to resources in another over the MNO’s network using their carrier IPs.

Maximum Transmission Unit (MTU) values for AWS Wavelength:

9,001 bytes between EC2 instances within the same AWS Wavelength Zone

1,500 bytes across the carrier gateway

1,468 bytes between an...
