Section 1: Bridging and Switching (16 Points)

Section 1.1: Frame Relay Configuration (6 Points)

• Configure the Frame Relay portion of the network as shown in Figure 2-11 and ensure that DLCIs 110 and 104 between R1 and R6 are not used.

  Figure 2-11. Frame Relay Diagram

  

  
  

• Use point-to-point subinterfaces with a number equal to that of 10 + the listed DLCIs.

• Ensure that the Frame Relay subinterfaces contain purely Layer 2 information, configure virtual Layer 3 addresses elsewhere for the Frame Relay connectivity, and make this connectivity as secure as possible. This configuration does not require any form of bridging.

• For IGP configuration, PVC 103-102 has a CIR of 512 kbps and PVC 101-100 has a CIR of 256 kbps. Use these figures appropriately as an IGP reference for the maximum capacity of the links.

Section 1.2: 3550 LAN Switch Configuration (9 Points)

• Configure VLAN numbers, VLAN names, and port assignment as per the topology diagram.

• Your customer has decided to test Voice over IP (VoIP) and is trialing Cisco 7960 and 7905 IP phones. The customer wants to take advantage of the auxiliary VLAN feature where possible. The 7960 is to be installed on port 0/16 and the 7905 on port 0/17. Use a separate VLAN for the voice of VLAN50 and assume that the customer will also require data access to VLAN2 for this trial; configure your switch appropriately.

• A server running Cisco CallManager and the associated IP requirements will also be installed with the IP phones and located in VLAN1; it will be reachable via the address of 172.16.0.10. You have been allocated the network 10.70.70.0/24 for the voice VLAN. You are not required to advertise the voice VLAN network but ensure you have configured your switch sufficiently so that if connected, the IP phones within this VLAN would be able to load their configuration files from CallManager.

• The customer also has a requirement to trial a standard OEM IP 10BASE-T telephone alongside the Cisco IP phones on port 0/18; configure your switch appropriately.

• Ensure the switch is reachable via the IP address of 10.80.80.8/24.

Section 1.3: ATM Configuration (1 Point)

• Configure the ATM PVCs as shown in Figure 2-12. Do not use subinterfaces and use the new format PVC vpi/vci when configuring the PVCs. Assume aal5snap; do not use the commands protocol ip destination address or broadcast under the PVC configuration mode.
