Microsoft Virtual Machine Issues w .1Q routing

Unanswered Question

Case study: I am seeking help as I am attempting to test the .1Q functionality of Microsoft Virtual PC (only). What I have done is connected a PC w 1gig NIC configured for .1Q tagging and connected it to a Cat 3750 trunk port. I configured 3 VLAN (one per virtual environment) and I created a loopback interface to ping too.

Problem: PING not successful. I am able to see the VLAN tagged on the 3750 and when I show ARP on the 3750 I do see the MAC of the Virtual PC with the correct VLANID but the switch will not route the packet to the LO int. Hence, PING failure. I tried with both no routing and with EIGRP both, to no avail.

Attached is a diagram with info, the IOS is LAN IP not sure version but there are no other config’s on the 3750 it is clean fresh out of the box. I have to use this set as I am limited additional devices due to security policies.

Any suggestions or recommendations would be greatly appreciated. I am leaning towards Microsoft VM the root cause but just not sure. The ping should route and respond.
