Configuration Example
of Frame Relay Traffic
Shaping
I. Configuration Requirements
The Router is connected to the Frame Relay network via the interface Serial 0. It is
required that the average transmit rate of the router should be 96 kbps, the
maximum transmit rate should be 128 kbps, and the minimum transmit rate
should be 32 kbps, and at the same time, the router should own the function of
adaptive traffic adjustment. In addition, PQ is required to be adopted to ensure
that all the IP packets from the segment 10.0.0.0 will pass first.

III. Configuration Procedure
1 Define priority queue Group 1, and request all the IP packets from the segment
10.0.0.0 can pass first.

Example
I. Networking Requirements
Two Frame Relay networks are interconnected via RouterA and RouterB, which are
connected via an IP network. Enable Frame Relay over IP on the two routers to
interconnect these two Frame Relay networks over the IP network.
