PACKET FORWARDING METHOD AND SYSTEM, AND RELAY AGENT DEVICE

摘要

The present invention provides a message forwarding method and system, and a relay agent device. The forwarding method includes: receiving a first DHCPv6 message from a DHCPv6 client through a layer-3 interface; generating a Relay-forward message, where the first DHCPv6 message is encapsulated into the Relay-forward message and an identifier of the layer-3 interface is added therein; and sending the Relay-forward message to a DHCPv6 server. With the technical solution of the present invention, the relay agent device can correctly forward messages, resources of global unicast addresses or site-local addresses can be saved, and layer-3 forwarding performance of the relay agent device can be improved.
