ip interface arpProxy
On a per-interface basis, enables or disables ARP proxy on a Multilayer
Switching Module. ARP proxy helps end stations on a subnetwork reach
remote subnetworks that do not have routing capabilities or a default
gateway configured.
Valid Minimum Abbreviation
ip i a
Important Considerations
■
When ARP proxy is enabled and an end station sends an Address
Resolution Protocol (ARP) request for a remote network, the module
determines if it has the best route and then answers the ARP request
by sending its own MAC address to the end station. The end station
then sends the frames for the remote destination to the module,
which uses its own routing table to reach the destination on the other
network.
■
When an interface is defined, the default ARP proxy state is
enabled
.
■
The end stations must view the entire network configuration as one
network (that is, by using a smaller subnet mask).
■
Evaluate prolonged use of ARP proxy because it has some drawbacks,
including increased ARP traffic and a need for larger ARP tables to
handle the mapping of IP addresses to MAC addresses.
