I have two 6509s connected via fiber and running layer three OSPF routed traffic between them just fine. I now have a situation where I need a Layer 2 connection between the switches as well, going across the single piece of fiber. Possible? I can not use an addition port. All traffic has to go across the fiber.
Is there a way to put a sub-interface on the fiber connection and assign that sub interface to the same layer 2 switchport vlan?
Thoughts?
