This feature introduces support for scaling both IPv4 and IPv6 hosts on our devices. Existing MDB profiles offer a maximum host scale of 128k with unique MAC rewrites. However, if hosts share the MAC rewrites, the scale can reach up to 204k. To address this issue, we are introducing a new MDB profile that will support a host scale of up to 192k when each host has a unique MAC rewrite. If hosts share the MAC rewrites, the scale can reach up to 256k.
