On a user-mode server I'm
running I occasionally run into the problem where a machine goes down and my ARP
table shows an (incomplete) entry for the server that went down. That
incomplete arp entry does not seem to go away even if I try deleting manually
with the arp -d command.
The incomplete arp entry is on
one of the tap devices (tap15) but entering 'arp -d -i tap15 ipaddr' doesn't
remove it. What's the arp command that I need to execute to delete the
incomplete arp entry?
