FRTS configuration example
Network requirements
As shown in Figure 48, the router connects to the FR network through Serial 2/0. Its average transmit rate
is 96 kbps, maximum transmit rate is 128 kbps, and minimum transmit rate is 32 kbps. Configure FRTS
on the router to adjust 20% of the BECN-flagged traffic every time.
Configure PQ to make sure that the IP packets sourced from the 10.0.0.0 network segment are
transmitted preferentially.
