Redundant links to one MAC/IP address?
How can one configure a network to have redundant links to a single NIC or MAC address? This would be called fault tolerant so that if one link failed the other link would still provide data. This would be 2 100BaseT links from a router/switch to a single NIC/IP address.
Would duplicate data be sent and the receiver somehow select one or would the router reconverge to the redundant link by sensing a link failure and reconveging to the backup?
Any thoughts or literature you might refer me to so that I could understand how to do this or if it can be done?
Thanks for any tips

You can have redudant connections, but each would be a separate NIC (with its own MAC address). Back in the telephone dialup days this was known as "shotgunning" (multiple dialup connections all pushing/pulling data at once). I know it can be done with ethernet, but haven't seen much on it.
