When you see a configuration or CLI command resembling fbsubnet+l (or syntax adding a mode to a subnet attachment), it typically refers to enabling Appliance Mode on a Transit Gateway attachment for a VPC containing firewall appliances. | Dataset | Backbone | Input size |

By using fixed-block allocation, FBSUBNET+L drastically reduces the size of routing tables on core routers. Instead of hundreds of small /28 routes, routers see aggregated FBSUBNET+L superblocks. This speeds up packet forwarding and reduces CPU load on enterprise hardware. Imagine you have a VPC with subnets dedicated

In a standard Transit Gateway VPC attachment, the traffic flow uses Equal Cost Multi-Path (ECMP) routing and flow hashing.

Let’s visualize where this component sits.

Imagine you have a VPC with subnets dedicated to your firewall (fbsubnet).
