Message Forwarding Method, System, and Relay Agent Device |
摘要 |
The present disclosure provides a message forwarding method and system, and a relay agent device. The forwarding method includes receiving a first dynamic host configuration protocol (DHCP) for Internet Protocol (IP) version 6 (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 (ID) of the layer-3 interface is added therein, and sending the relay-forward message to a DHCPv6 server. |

1. A method for forwarding message, comprising:
receiving, by a relay agent device, a first dynamic host configuration protocol (DHCP) for Internet Protocol (IP) version 6 (DHCPv6) packet from a user device through an interface on the relay agent device; generating, by the relay agent device, a relay-forward message comprising a relay-message option, a first interface-identifier (ID) option and a second interface-ID option, wherein both the first interface-ID option and the second interface-ID option are in compliance to option 18 defined in request for comments (RFC) 3315, wherein the relay-message option encapsulates the first DHCPv6 packet, wherein the first interface-ID option indicates an ID of a port on the relay agent device on which the first DHCPv6 packet is received, and wherein the second interface-ID option indicates an ID of the interface on which the first DHCPv6 packet is received; and sending, by the relay agent device, the relay-forward message to a DHCPv6 server. |
