Actually I have not heard that argument. It depends on what you are doing
and the requirements. We have a 6 switch layer 2 core that feeds our Layer 3
distribution switches and our L3 distribution swiches have layer 2
redundancy with our access switches but run HSRP to provide L3 redundancy to
the stations hanging of the layer 2 closet access switches.
I have never heard arguments against layer 2 redundancy. I believe in a well
designed high reliable network from end to end you would need a combination
of both layer 2 and layer 3 redundancy and they go hand in hand to produce a
healthy, available and efficient network.

Hi,
Is the major argument against layer 2 redundancy (vs. layer 3 & HSRP) the
potential for layer 2 loops and problems with spanning tree. So I take it
layer 3 is the best way to go in the industry.
Thanks
