Adding Breakout Profiles

You use the Add Breakout Profile page to add a local breakout (underlay), backhaul, or a cloud breakout profile. A cloud breakout profile is added by Contrail Service Orchestration (CSO) by default.

To add a breakout profile:

  1. Select Configuration > SD-WAN > Breakout Profiles.

    The Breakout Profiles page appears.

  2. On the Breakout Profiles tab, click the add icon (+).

    The Add Breakout Profile page appears.

  3. Complete the configuration according to the guidelines provided in Table 1.
    Note:

    Fields marked with an asterisk (*) are mandatory.

  4. Click OK.

    You are returned to the Breakout Profiles page (Breakout Profiles tab) and a confirmation message indicating that the breakout profile was added is displayed. The page refreshes to display the breakout profile that you added.

    Note:

    After you add a breakout profile, you must add an SD-WAN policy intent that references the breakout profile in order to enable breakout traffic.

Table 1: Fields on the Add Breakout Profile Page

Field

Description

Type

Select the type of breakout profile that you want to add:

  • Local Breakout (Underlay)—Select this option if you want traffic to break out locally (on the underlay) from the site.

  • Backhaul—Select this option if you want traffic to break out through a hub or a enterprise hub (if configured).

  • Local Breakout (Cloud)—Select to break out traffic through a cloud-based security platform. Currently, Zscaler is the only cloud-based security platform supported.

Name

Enter a unique name for the breakout profile. You can use alphanumeric characters and hyphens (-); the maximum length is 15 characters.

Description

Enter a description for the breakout profile.

Traffic Type Profile

Select a traffic type profile to apply class of service parameters to the breakout traffic. You can select only a traffic type profile that is enabled.

Preferred Path

Select the preferred path (MPLS, Internet, or Any) to be used for breaking out the traffic.

If a WAN link type that matches the preferred path is enabled for breakout, then that WAN link type is used for breakout traffic.

If you specify that any path can be used, then there is no preference and all breakout-enabled links are used in a load-balancing mode.

Advanced Configuration

  

Rate Limiting

Click the toggle button to enable rate limiting of breakout traffic for cacheable applications. By default, rate limiting is disabled.

If you enable rate limiting, you must specify the upstream and downstream parameters, and the loss priority.

Upstream Rate

Specify the maximum upstream rate (in Kbps) for all cacheable applications associated with the breakout profile.

Upstream Burst Size

Specify the maximum size (in bytes) of a steady stream of traffic sent at average rates that exceed the upstream rate limit for short periods.

Downstream Rate

Specify the maximum downstream rate (in Kbps) for all cacheable applications associated with the breakout profile.

Downstream Burst Size

Specify the maximum size (in bytes) of a steady stream of traffic sent at average rates that exceed the downstream rate limit for short periods.

Loss Priority

Select a loss priority based on which packets are dropped or retained when network congestion occurs. Packet drops are most likely when the loss priority is High and least likely when the loss priority is Low.
