Thanks, Chris.

I considered this simple setup, but I was told that one should never pass
"real" traffic through the management VLAN1.  Is that really not the case?

I am not running HSRP.  The two 6509/Sup720s are in two different cities.  I
was unable to get dark fiber between the two locations, so the switch in the
middle is sitting in the CO where I am given a GigE connection going out to
each of my pieces of equipment.  It's a long, stupid political reason.  No
technical reason why I was unable to connect the two switches directly
together.
