AI Technical Summary

Problems solved by technology

The IPv6 client may use the RA packet sent by IPv6 server 1 and the DHCPv6 packet sent by IPv6 server 2 during IPv6 address configuration. At this time, the IPv6 client may use IPv6 server 1 as the default Obtain the address and DNS information on server 2, which will cause routing failure or detours
[0005] To sum up, when there are multiple DHCPv6 servers and multiple routers on a link, IPv6 clients may use RA packets and DHCPv6 packets confusingly, resulting in routing failure or detours

Embodiment 1

[0067] Figure 1a A flow chart showing a method for configuring an IPv6 address according to Embodiment 1 of the present invention. Such as Figure 1a As shown, the IPv6 address configuration method mainly includes:

[0068] Step 100, the IPv6 client receives a route broadcast RA message from the router at the IPv6 server end, the RA message includes server information of the DHCPv6 server at the IPv6 server end, and the server information includes the server address of the DHCPv6 server.

[0069] Specifically, if there are multiple DHCPv6 servers and multiple routers in one link, the DHCPv6 servers and routers can be set on different devices, or they can be set on the same device. The IPv6 server end in the embodiment of the present invention may include a DHCPv6 server and a router. The IPv6 route discovery protocol is composed of two Internet Control Message Protocols (Internet Control Message Protocol, ICMP6) for route request RS and route broadcast RA. The device can ...

Embodiment 2

[0079] figure 2 A flowchart showing the IPv6 address configuration method according to Embodiment 2 of the present invention. figure 2 Winning mark and Figure 1a The same steps have the same functions, and detailed descriptions of these steps are omitted for brevity.

[0080] Such as figure 2 as shown, figure 2 For the shown IPv6 address configuration method, only the parts different from those in FIG. 1 will be described in detail below. For the parts that are the same as those in FIG. 1 , refer to the specific description of FIG. 1 .

[0081] Optionally, the server information may also include a first server ID, and the DHCP response may also include a second server ID, where the first server ID is the server ID of the DHCPv6 server stored in the router, and the second server ID is the DHCPv6 server that returns the DHCP response. The server ID of the server. Step 140 may specifically include:

[0082] Step 240, when the first server identifier is the same as the ...

Embodiment 3

[0094] image 3 A flowchart showing the IPv6 address configuration method according to Embodiment 3 of the present invention. Such as image 3 As shown, the IPv6 address configuration method mainly includes:

[0095] Step 300, the router at the IPv6 server end sends a routing broadcast RA message to the IPv6 client, the RA message includes server information of the DHCPv6 server at the IPv6 server end, and the server information includes the server address of the DHCPv6 server.

[0096] Specifically, during the process of the IPv6 client acquiring address and network information (such as routing, DNS, etc.), the router at the IPv6 server end can send a route broadcast RA message to the IPv6 client end, and the RA message includes the IP address of the DHCPv6 server at the IPv6 server end. Server information, the server information may include the server address of the DHCPv6 server, which is used to send a DHCP request to the DHCPv6 server in a unicast manner to realize the ...

Abstract

The invention discloses an IPv6 address collocation method, an IPv6 client and a server. The method comprises the steps that the IPv6 client receives an RA message from a router, the RA message comprises server information of the DHCPv6 server, and the server information comprises a server address of the DHCPv6 server; the IPv6 client sends a DHCP request to the DHCPv6 server according to the server address; the IPv6 client conducts address collocation according to a DHCP response fed back from the DHCPv6 server. According to the IPv6 address collocation method, the RA message comprises the server address of the DHCPv6 server, the IPv6 client sends the DHCP request according to the server address, when a multi-routing phenomenon exists in the same link, the IPv6 client routes the correct DHCPv6 server, the DHCP response is obtained from the correct DHCPv6 server, and correct routing information can be rapidly obtained.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to an IPv6 address configuration method, an IPv6 client and a server. Background technique [0002] With the exhaustion of Internet Protocol (Internet Protocol, referred to as IP) version 4 (IPv4) addresses and the increasing difficulty of maintaining the backbone routing table, more and more operators are beginning to try to deploy the sixth version of IP (IPv6). Compared with the dynamic address acquisition method of IPv4, the dynamic address acquisition method of IPv6 has undergone great changes. IPv4 can obtain addresses dynamically only by the dynamic host configuration protocol (Dynamic Host Configuration Protocol, referred to as DHCP) interaction process. IPv6 considers When it comes to wireless and managing a large number of devices, the Stateless Address Auto Configuration (SLAAC) method is introduced for address configuration, so in the process of address, domain nam...
