Instead, Koch’s engineering team set about virtualizing the physical transports to build the SD-LAN and firewall within the cloud rather than in the data center. Leased lines and direct connects would remain in the data center as part of this strategy, but Hoag did not want to route users through the data center to access data on the cloud.

All of these messages derive from the assumption that one subnet = one security zone, and therefore intra-subnet communications are not secured. If the router sends RA messages without any prefixes, then devices are forced to send their packets to the router—which can then enforce any necessary security issues.
