Feature Overview
Border Gateway Protocol (BGP) policy accounting measures and classifies IP traffic that is sent to, or
received from, different peers. Policy accounting is enabled on an input interface, and counters based on
parameters such as community list, autonomous system number, or autonomous system path are
assigned to identify the IP traffic.
received from, different peers. Policy accounting is enabled on an input interface, and counters based on
parameters such as community list, autonomous system number, or autonomous system path are
assigned to identify the IP traffic.
Using the BGP table-map command, prefixes added to the routing table are classified by BGP attribute,
autonomous system number, or autonomous system path. Packet and byte counters are incremented per
input interface. A Cisco IOS policy-based classifier maps the traffic into one of eight possible buckets,
representing different traffic classes.

Using BGP policy accounting, you can account for traffic according to the route it traverses. Service
providers (SPs) can identify and account for all traffic by customer and bill accordingly. In
