One of the most important improvements of Cisco SD-WAN over the Traditional WAN architecture is the ability to reroute application traffic around WAN performance degradations and brownout conditions such as packet loss, latency, and jitter.
It is pretty common that an organization has branches where guest users are permitted to connect to the network and provided Direct Internet Access (DIA). As a rudimentary security measure, the guests can be confined within their own VPN.
A Centralized Data Policy allows network administrators to override the normal forwarding decisions that would occur at specific WAN edge routers and define a different set of actions that would be performed instead.
Cisco WAN Edge routers periodically send and receive OMP updates with the vSmart controllers. These OMP updates contain vRoutes, TLOC, or Service routes. When a vSmart controller receives an OMP route from a vEdge, it performs the OMP best-path algorithm and updates its own routing table.
Before we start with this lesson, I'd like to quickly explain some terms and concepts upfront.
In Cisco SD-WAN, you can apply configurations to network devices with either one of the following two methods:
Each section ends with a Quiz that is designed to give you feedback on your progress. If you have a low score, consider retaking all lessons in this section. If you pass with a high score, go to the next section and continue toward achieving your goal.
The quiz takes only 5 minutes! Good Luck!
