Claim:
1. A method for eliminating slow switching paths comprising: installing one or more subnet prefixes pointing to a multicast set at one or more remote switches within a first subnet such that a single multicast group is created for the first subnet, wherein the single multicast group comprises only leaf switches that have membership in the first subnet; sending a first packet to all remote switches in the multicast set; forwarding the first packet from a first remote switch in the multicast set only in the case of a local destination Internet Protocol (IP) hit at a forwarding information base (FIB) table associated with a second remote switch; dropping the first packet at the second remote switch in the multicast set after a miss at a FIB table associated with the second remote switch; and dropping the first packet at a third remote switch in the multicast set after a hit at a FIB table associated with the third remote switch, wherein the hit is for a non-local destination.
