[0026] The packet processing unit, the ARP entry for the neighbor edge device decapsulates the transmitted packet deletion, deleting the local cache entry is deleted ARP packet carrying the ARP entry corresponding to the MAC address aging; [0028] Further, the entry is deleted ARP packet source IP address is the IP address of the host MAC address aging, the aging of the source MAC address is the MAC address, destination IP address is a predetermined IP address, destination MAC address MAC is a broadcast address; [0029] The packet processing unit processes the ARP cache entry is deleted locally remove the ARP entry packet carries MAC address aging comprises: deleting the local cache entry is deleted ARP packet source IP address and source MAC address of the ARP entry relationship.[0033] The ARP aging carries the MAC address entry is deleted packet, to receive an indication to delete the ARP entry packet stored deleting the local host aging ARP entry corresponding to the MAC address.

[0089] Specifically, the edge switches A and C at the edge switch receives the ARP entry is deleted packets sent after the edge switch B, decapsulates the MAC address and the source from which to obtain the ARP entry is deleted packet, i.e., host MAC address aging MAC_B1 BI, and a source IP address, i.e.

MAC address aging BI host IP address corresponding MAC_B1 IP_B1.

[0067] In a third embodiment, in a networking environment shown in Figure 1 as an example, when the host the MAC address of aging can be constructed to delete the message ARP entry, and then delete the ARP entry packet to the edge device to implement networking buffers aging MAC address and host network devices update their ARP cache entries.

[0069] In in EVI network, the MAC address is usually allocated dynamically, when reaching the own MAC address aging time, or when the host is forced aging own MAC address, the host needs to delete corresponding to the own MAC address and IP address relationship.

[0018] The ARP aging carries the MAC address entry is deleted packet, to receive an indication to delete the ARP entry packet stored deleting the local host aging ARP entry corresponding to the MAC address.

[0023] The message forwarding unit, configured to send to the neighbor edge device after deleting the ARP entry tunnel encapsulation packet to indicate that the neighbor edge device to delete the local cache entry is deleted ARP packet carries aging MAC address of the corresponding ARP entry, and the entry is deleted ARP broadcast packet to its local host.

Thus, in the site A or A2 host from other hosts again ARP request packet request to obtain the MAC address of the BI, the edge switch A local ARP cache lookup, the ARP request packet transmits an ARP response packet.

Further, even if the configuration of the ARP entry survival time is less than the survival time of the MAC address, the MAC address of the host if the compulsory aging, such as: to clear or modify the mapping between the MAC address and IP address, or may cause a black hole.

The present invention is designed by the host when the MAC address of aging, constructed to delete the ARP entry packet to notify other network devices ARP entry, and delete the host network in the local cache corresponding to the MAC address aging.

[0079] The present invention is constructed in the ARP packet deleting entries, which define the type of operation to OP 3, source MAC address is the MAC address aging, a MAC address of the source IP address corresponding to the aging IP address, destination MAC address F for the whole broadcast address, destination IP address of the default IP address.

According to the technical scheme, a flow black hole caused by aging of the MAC address is avoided and the complexity of the process that the APR cache aging time is manually configured by a network manager is reduced.
