Hi,

Could I drop hardware Layer 2 switching entirely, and route traffic directly 
from the hypervisor/ospf ?

I'm trying to eliminate STP, utilize multiple links, avoid downtime during 
upgrade of switch-stack etc I was wondering if the following would be possible:

Uplink       Uplink
  |            |
  |            |
Router1 ---- Router2    
  |   \    /   | 
  |    \  /    |
  |     \/     |
  |     /\     |
  |    /  \    |
  |   /    \   |
Server1 ---- Server2    
  | |         | |
  | |         | |
  OVS         OVS        
   |           |
   |           |
  VM          VM

Routers and Servers run OSPF - the only layer 2 traffic is inside openvswitch 
<-> VM

But does OVS depend on layer2 hardware interfaces to function?
I don't see how OVS would handle the two interfaces without layer2 access for 
bonding, so this is probably a long shot ? :-)

Regards
Kristoffer
