Delivering Internet-bound traffic to the Internet UCS based on policy is accomplished by Internet Breakout (local Internet breakout). In SD-WAN, policies decide where traffic should exit the overlay. When a rule specifies that Internet-bound packets should exit locally, the Internet Breakout function routes those egress packets from the SD-WAN Edge directly to the Internet surface at the site (the Internet UCS), rather than sending them through a central data center. This enables direct, policy-driven Internet access from the branch. The other options don’t provide the mechanism for exiting to the Internet by policy: the underlay connectivity services handle transport, not egress decisions; the inter frame gap is a low-level Ethernet timing detail; and the SD-WAN Edge is the device that enforces policies, but the actual exit point to the Internet is the Internet Breakout mechanism.
