there's a couple of things worth pointing out about Hyper-V deployments of BIG-IP VE:
(These can be found in the manual too, but here's a concise little guide):
1) You can have up to four Legacy Network Adapters assigned to the BIG-IP VE Hyper-V Virtual Machine container. You'll probably want three at a minimum for an Internal and External network, but BIG-IP is quite flexible and will fit 1 to 3 data plane interfaces handily.
2) To use a VLAN tag:
2.1) VLAN tags can be configured on the Legacy Network Adapter (Hyper-V configuration)
- open the nic on the vm
- [x] Enable virtual LAN identification
- Put in a VLAN ID value to use for tags
2.2) Configure VLANs to use untagged interfaces (BIG-IP configuration)
2.3) Configure the receiving device to accept and send the correct VLAN tags (switch, router, BIG-IP hardware, Hyper-V server, etc.)
