Configuring QPPB

The QPPB feature enables you to classify IP packets based on BGP community lists, prefix lists, and BGP AS
paths.
With QPPB, the BGP route sender preclassifies routes before advertising them, and the BGP route receiver
sets the IP precedence and QoS-local ID for the routes and takes appropriate QoS actions on packets
matching the routes.
QPPB minimizes the QoS policy configuration and management efforts on the BGP route receiver when the
network topology changes. It is suitable for a large-scaled complex network that classifies packets based on
source or destination IP addresses for QoS.
QPPB applies to IBGP and EBGP. Use it within an autonomous system or across multiple autonomous systems.

Fundamentals

QPPB works on the BGP receiver. It depends on the BGP route sender to preclassify routes.
The BGP route sender uses a routing policy to set route attributes for BGP routes before advertising them.
The BGP receiver uses a routing policy to match routes based on these route attributes, and sets an IP
precedence and QoS-local ID for the matching routes:
