Ah... vPC's to BigIP's work fine... They don't even know that there's a vPC involved because the vPC is at the Nexus end. The BigIP end if just a normal BigIP LACP trunk.

 

 

FWIW I have vPC's to lots of devices (Including BigIP LTM's, Checkpoint VSX's) from nexus 7010's on both 10Gb and 1Gb links. They work fine. A little strange when debugging, because they show a few funny bots about MAC addresses and the ports they see it down, but that's at he nexus end.

 

 

Also be careful of the terminology between Cisco and F5 equipment. A Cisco Trunk is F5 VLAN Tagging. A Cisco Port-Channel (Or even ether channel depending on IOS/NX-OS version) is an F5 Trunk... So if you just say 'Trunk' it's a bit ambiguous (And very prone to confusion. try getting some Cisco and F5 guys together in a room to talk about link aggregation and watch the confusion start :)
