Dot1q trunk across a vlan

Hi all,

Currently, I am trying to design a network with 1) internet access, and 2) a point to point link with another location. My ISP is going to handle the point to point and internet connection over wireless equipment (the new building is in a non-servicable area). From my understanding, they're going to bring a dot1q trunk with 2 vlans into the building with the wireless, 1 vlan for internet, and the other for point to point. However, I have 2 vlans that I need access to at both locations (voice and data). Is it possible to bring in the trunk from the ISP to a catalyst 3560, split the vlans off, and then create another trunk into the point to point vlan? If so, how would I manage this?

Yes, you can do that. The problem would be prioritization on the wireless link. Make sure the ISP will prioritize traffic marked EF and you should be OK.
