Breakout and Breakout Profiles Overview

Site-to-site traffic between spoke sites of a tenant is sent (on overlay tunnels) directly from one site to another depending on the tenant topology or through the hub or gateway site. However, for Internet-bound or Software as a Service (SaaS) traffic, you can break out the traffic in different ways:

In CSO Release 4.0, only local breakout and central breakout (backhaul) are supported and the breakout option is enabled only at the site level. However, from CSO Release 4.1.0 onward, breakout is supported at the site, department, and application (cacheable only) levels by using breakout profiles that are applied using SD-WAN policy intents. Non-cacheable applications follow the site-specific or department-specific behavior as configured in the SD-WAN policy intent.

Note For sites added in CSO Release 4.1.0 onward, you cannot configure breakout directly at the site level and must use breakout profiles referenced in SD-WAN policy intents for this purpose.

Breakout Profiles

The following three types of breakout profiles are supported in CSO:

After you add a breakout profile, you must create an SD-WAN policy intent specifying the source (site, site group, or department) and application and the applicable breakout profile.

SD-WAN Policy Intents for Breakout and Precedence

For SD-WAN policy intents configured at different source endpoints, the following is applicable:

An example of the precedence of SD-WAN policy intents for breakout (from highest precedence to lowest precedence) is provided in Table 121. The SD-WAN policy intent number 1 has the highest priority and SD-WAN policy intent number 7 has the lowest priority.
