Target Hardware Address * (In the ARP portion of the packet) * * a) ARP Reply * * Set to the MAC address we want associated with the VIP, * as per RFC2002 (4.6). * * Previously set to ff:ff:ff:ff:ff:ff * * b) ARP Request * * Set to 00:00:00:00:00:00. According to RFC2002 (4.6) * this value is not used in an ARP request, so the value should * not matter. However, I observed that typically (always?) this value * is set to 00:00:00:00:00:00. It seems harmless enough to follow * this trend. * * Previously set to ff:ff:ff:ff:ff:ff * * 2. Source Hardware Address * (Ethernet Header, not in the ARP portion of the packet) * * Set to the MAC address of the interface that the packet is being * sent to. Actually, due to the way that send_arp is called this would * usually (always?) be the case anyway. Although this value should not * really matter, it seems sensible to set the source address to where * the packet is really coming from. The other obvious choice would be * the MAC address that is being associated for the VIP. Which was the * previous values.
