I have hit a problem with using VLAN IDs on Hyper-V VM's.
We have two physical locations and each location has a Hyper-V cluster. These locations are linked by a 1Gb connection. We are running a spanned ip subnet across these sites and this spanned subnet is using the VLAN ID 4094. Ethernet switches have full connectivity to all devices on the 4094 network in both locations. Hyper-V hosts have full connectivity to all devices on 4094. Hyper-V hosts are connected to trunk ports that allow 4094
However my problem is, i have a VM in each site on Hyper-V that has 4094 specified in the network adapter settings of the VM. The VM in location 1 can see all devices on the 4094 VLAN except the Hyper-V based VM in location 2 and likewise the VM in location 2 can see all devices on 4094 except the VM in location 1.
Anybody know if VM's on different clusters cannot use the same vlan id?
