ADDRESS RESOLUTION PROTOCOL (ARP) TABLE ENTRY CONFIGURATION METHOD AND DEVICE

摘要

Embodiments of the present invention disclose a method and an apparatus for configuring an ARP entry. The method includes: acquiring, by a first router, when determining that a second router is a reachable neighbor, information needed for configuring an ARP entry; and configuring, by the first router during neighbor route calculation performed with the second router, the ARP entry according to the acquired information needed for configuring the ARP entry. When neighbor establishment between the first router and the second router is completed, because the ARP entry configuration on neighbor routers has been completed and IP traffic can be forwarded normally, the problem that partial traffic is lost when the neighbor routers perform traffic forwarding for the first time is avoided.
