Summary

Added 'VPN Concentrator' as a transit gateway attachment type and updated terminology from 'AWS Direct Connect' to 'Direct Connect' in MTU section.

Security assessment

The change adds a new attachment type (VPN Concentrator) but provides no security context. Terminology updates for Direct Connect are branding changes with no security implications.

-  * Transit gateway Maximum Transmission Unit (MTU) — The maximum transmission unit (MTU) of a network connection is the size, in bytes, of the largest permissible packet that can be passed over the connection. The larger the MTU of a connection, the more data that can be passed in a single packet. A transit gateway supports an MTU of 8500 bytes for traffic between VPCs, AWS Direct Connect, Transit Gateway Connect, and peering attachments (intra-Region, inter-Region, and Cloud WAN peering attachments). Traffic over VPN connections can have an MTU of 1500 bytes.
