Re: hot standby

If you have properly designed network with dual core and all your other closet/distribution switches dual attached to core switches, you can make core switches redundant. Layer 2 redundancy is taken care by Spanning tree and for layer 3 redundancy, you can use HSRP

The layout should look something like the one in the following page
