IBGP Accounting Example
In the example below, routers R1 and R2 are running IBGP/RIP, so they exchange routes automatically. Customer
traffic from 13.1.1.5 is being routed to the destination 14.1.1.1/16. The customer is connected to router R1 through
the interface ’customerA.’ The route to 14.1.0.0/16 is a direct route on router R2 and is learned by R1, which sets the
traffic index to 1.

The following configurations enable BGP accounting on interface ’customerA’ to tally the number of bytes and packets
