The above network design is recommended. The explanation is as follows:
• Branch router incoming traffic is controlled by HQ router’s frame relay PVC to
branch router Bc and Be definition.
• Branch router incoming traffic is only from HQ router’s frame relay PVC. There
is no possibility to be interleaved with other PVC traffic.
Figure 5 gives more information about the network design.
