Rag-Tag Books has asked you to assist them in converting from their full-mesh ATM network (shown in Figure 7.45) to an MPLS VPN. Each store has four connections. They are running a variety of ATM traffic, with uncommitted information rate comprising most of their traffic. However, QoS is required for the 10 percent of their traffic that runs the SAP database.
| 1. | Is MPLS VPN service appropriate, and if so, why? | |
| 2. | Which MPLS VPN service is recommended? | |
| 3. | How do you justify your recommendation? | |
Answers
| 1. | Fully meshed networks could produce a cost justification for MPLS service. |
| 2. | In order to recommend a VPN service, you would need to know whether the interfaces are Layer 2 or Layer 3. Additional information is needed |
| 3. | Further study is needed to make a VPN recommendation. No recommendations were made because the interfaces and requirements ere not clearly defined. |
