Layer 3 Routing Commands 1194
The interface identifier is the identifier of the unnumbered interface, not the
loopback interface from which the IP address is borrowed.
When the IP address does not uniquely identify an ARP entry, the interface
must be given to uniquely identify the ARP entry. The interface may be
numbered or unnumbered.
Example
The following example removes the specified IP address from arp cache.
console#arp purge 192.168.1.10
