I know that this LAB was just posted yesterday in the member site and is not in its final form yet... but, I would like to ask the Brians for their opinion on my solution for task 1.1 and 1.2.
First for task 1.1, the VLAN tables are inaccurate in respect to the topology. So, I drew out my own Layer 2 topology and assigned them accordingly in respect to the LAB diagrams. Then I configured the vtp version to be V2, so that SW4 can pass the VTP advertisement to SW1. (Relaying the advertisements across separate VTP domain) I also made sure that all transit vlans were configured on SW4 (transparent switch)
For task 1.2, I configured the trunk links on the Router 4 side using the VLANs given in the task. On the respective Switch side, I configured QinQ tunnel ports using the metro tags mentioned in the task.
To complete the task, I used 2 unused inter-switch links between SW1 and SW3 and configured trunks and tunnel port pairs needed to finish the QinQ tunnel. On SW3, I only allowed vlan 45 on fa0/13 and vlan 54 on fa0/14 trunk links. On SW1, I configured tunnel ports using the respective metro tag VLANs (fa0/16 vlan 245 and fa0/17 vlan 254) Then, finally I configured the trunk link between SW3 and R5 allowing only vlan 45 and 54. Also, I removed vlan 245, 254, 54, and 45 from the trunk link between SW2 and SW3 to allow the traffic to only flow as intended.
In conclusion, the traffic will flow like this:
1, R4 vlan 45 and vlan 54 will receive their respective metro tags as they
enter the Layer 2 domain.
2. The Traffic will be forwarded out the respective egress points on the SW1 and their metro tags will be stripped off
3. Within SW3, the traffic will forwarded out the trunk link between SW3
and R5

Sorry for the Long Email. My LAB date is in 2 days, and any input will be greatly appreciated. Also, I haved also verified the configurations for connectivity between all ethernet segments. I just wanted to know what kind of solution you had in mind for the task and your opinion on mine.
