METHOD FOR STUDYING MAC ADDRESS AND NETWORK ELEMENT APPARATUS

WIPO Patent Application WO/2009/003394

A1

A method for studying a MAC address comprises: in the received ARP reply message with multi identical source IP addresses and different source MAC address, the VRRP standby router can detect the ARP reply message whose source IP address is not the IP address of the current router, but whose source MAC address is the virtual MAC address of the current router; wherein, the format of the virtual MAC address is 00-00-5E-00-01-{VRID}; according to the mapping relation between the MAC address in the hardware address resolution protocol list and the IP address in the software address resolution protocol list, the source MAC address in the ARP reply message whose source MAC address is not the virtual MAC address is refreshed into the hardware address resolution protocol list, and the ARP reply message whose source MAC address is the virtual MAC address is neglected. Using the technical scheme can make the standby router study the correct MAC address.
