The Expire entry is the result of FreeBSD's unfortunate co-mingling network layer routing information with layer 2 ARP information. The only entries with "Expire" values are actually ARP entries. (Note the MAC address os "Gateway".) Expire is in seconds remaining until the entry expires and is no longer used. -- R. Kevin Oberman, Network Engineer Energy Sciences Network (ESnet) Ernest O.
