In one embodiment, a switch in a computer network intercepts a packet to a destination target, the packet having a solicited node multicast address of the target as a destination media access control (MAC) address of the packet. As such, the switch may determine whether the solicited node multicast address is a hit or miss within a switch hardware table of the switch, and in response to a hit, re-writes the destination MAC address with a known value of the destination target from the table, and unicasts the packet to the destination target. In one or more additional embodiments, in response to a miss, and in response to a single-switch architecture, the switch drops the packet, while in response to a miss, and in response to a multi-switch architecture, the switch may compute a repository switch for the solicited multicast destination, and unicasts the packet to the computed repository switch. |

1. A method, comprising:
intercepting, at a switch in a computer network, a packet to a destination target, the packet having a solicited node multicast address of the target as a destination media access control (MAC) address of the packet; determining whether the solicited node multicast address is a hit or miss within a switch hardware table of the switch; in response to a hit, re-writing the destination MAC address with a known value of the destination target from the table; and unicasting the packet to the destination target. |
