Customizing Global ARP
You can use the BCC or Site Manager to do the following:
• Control how ARP acts in relation to IP’s forwarding state.
• Control whether IP drops and logs an invalid ARP source address or simply
drops the request.
• Control whether IP drops or accepts ARP requests in which the source and
destination addresses are located in different networks or subnetworks. This
parameter allows Proxy ARP to generate replies when the source and
destination networks in the ARP request differ.
