Information About Configuring Path Preference

Minimum releases: Cisco IOS XE Catalyst SD-WAN Release 17.9.1a, Cisco vManage Release 20.9.1

When configuring a centralized policy, you can create a preferred color group list, which specifies three levels of route preferences, called primary, secondary and tertiary. The route preferences are based on either or both of the following:

TLOC color
Path type (direct tunnel, multi-hop path, or all paths), which is relevant to networks using Multi-Region Fabric

When you configure an application-aware routing (AAR) policy or a traffic data policy, you can use the preferred color group list in the action portion of a sequence to specify how to route the matched traffic.

Sequence of Steps

1. Create a preferred color group list.
2. In the preferred color group list, specify the path preference—direct tunnel or multi-hop path.
3. Use the preferred color group list in an AAR policy or traffic data policy.

The result is that the policy applies the path preferences that you have configured in the preferred color group list.
