CoS-based forwarding and policy-based routing to steer selective traffic over an SR-TE path

You can use CoS-based forwarding (CBF) and policy-based routing (PBR, also known as filter-based forwarding or FBF) to steer service traffic using a particular segment routing-traffic-engineered (SR-TE) path. This feature is supported only on uncolored segment routing LSPs that have the next hop configured as a first hop label or an IP address.

With CBF and PBR, you can :

• Choose an SR-TE path on the basis of service.
• Choose the supporting services to resolve over the selected SR-TE path.
