背景技术Background technique
IPv4(Internet Protocol version 4，网际协议版本4)是互联网协议的第四版，也是第一个被广泛使用，构成现今互联网技术的基石的协议。随着IPv4地址的耗尽以及使用IP地址的设备越来越多，出现了下一代互联网协议IPv6(Internet Protocol Version 6，网际协议版本6)，IPv6是IETF(InternetEngineering Task Force，互联网工程任务组)设计的用于替代现行版本IP协议(IPv4)的下一代IP协议。IPv6的设计被认为是IPv4革命性的一步，它继承、保留、修改、完善和扩展了IPv4协议，能够无限地增加IP(Internet Protocol，互联网协议)网络数量，拥有巨大的地址空间和卓越的网络安全等特点，不仅能够满足互联网飞速发展的需求，即插即用的接入方式、网络层的认证与加密、对服务质量和移动IP的支持，使其成为构造下一代互联网络的最佳选择。而用于将家庭网络和Internet连接起来的家庭网关在支持IPv6后，由于各种业务开展的需要，需要对家庭网关的LAN(Local Area Network，局域网)侧的桥端口和WAN(Wide Area Network，广域网)侧的WAN连接进行绑定，桥端口下的设备访问Internet时可以走不同WAN连接，从而开展各种各样的业务。在动态改变这些绑定关系后，由于绑定所做的工作仅仅是控制报文在桥内的转发，而桥端口下设备的网络参数如缺省路由、DNS(Domain Name System，域名系统)以及全局地址等都没有被及时更新，需要手动配置或者重启设备，增加了桥端口下设备使用网络的复杂度，以及给客户带来了不便。IPv4 (Internet Protocol version 4, Internet Protocol version 4) is the fourth version of the Internet protocol, and it is also the first widely used protocol that constitutes the cornerstone of today's Internet technology. With the exhaustion of IPv4 addresses and more and more devices using IP addresses, the next generation of Internet Protocol IPv6 (Internet Protocol Version 6, Internet Protocol Version 6) has emerged. IPv6 is an IETF (InternetEngineering Task Force, Internet Engineering Task Force) A next-generation IP protocol designed to replace the current version of the IP protocol (IPv4). The design of IPv6 is considered to be a revolutionary step of IPv4. It inherits, retains, modifies, improves and expands the IPv4 protocol, and can increase the number of IP (Internet Protocol, Internet Protocol) networks infinitely. It has a huge address space and excellent network Features such as security can not only meet the needs of the rapid development of the Internet, plug-and-play access methods, authentication and encryption at the network layer, support for quality of service and mobile IP, making it the best choice for constructing the next generation Internet . After the home gateway used to connect the home network and the Internet supports IPv6, due to the needs of various business development, it is necessary to check the bridge port on the LAN (Local Area Network, local area network) side of the home gateway and the WAN (Wide Area Network, The WAN connections on the WAN) side are bound, and the devices under the bridge port can use different WAN connections when accessing the Internet, so as to carry out various services. After dynamically changing these binding relationships, because the work done by the binding is only to control the forwarding of messages in the bridge, the network parameters of the devices under the bridge port, such as default routing, DNS (Domain Name System, Domain Name System) and The global address and so on have not been updated in time, requiring manual configuration or restarting the device, which increases the complexity of using the network for devices under the bridge port and brings inconvenience to customers.

The router advertisement message includes the DNS information (DNS address) before the binding relationship is changed, the default routing time and prefix information (preferred time and valid time of the prefix), and sets the invalid flag for the above information; The WAN connection is a routing connection, and the router advertisement message also includes DNS information and prefix information obtained from the WAN connection after the binding relationship is changed.
步骤S102，家庭网关桥端口下设备接收所述路由器通告报文，根据所述路由器通告报文，对其网络参数进行配置。网络参数是指家庭网关桥端口下设备的DNS、缺省路由和前缀等参数。对于绑定关系改变后WAN连接是路由连接的，利用路由器通告的特点，自动更新桥端口下设备的网络参数；对于绑定关系改变后WAN连接是桥接方式的，家庭网关桥端口下设备可以自动更新网络参数。Step S102, the device under the bridge port of the home gateway receives the router advertisement message, and configures its network parameters according to the router advertisement message. Network parameters refer to parameters such as DNS, default route, and prefix of the device under the bridge port of the home gateway. If the WAN connection is routed after the binding relationship is changed, the network parameters of the device under the bridge port will be automatically updated by using the characteristics of the router notification; if the WAN connection is bridged after the binding relationship is changed, the device under the bridge port of the home gateway can be automatically updated. Update network parameters.
在上述步骤S101中，当绑定关系改变前后WAN连接均为路由连接时，路由器通告报文中的缺省路由时间时间为设定时间，源地址为桥的地址；将在绑定关系改变前从WAN连接获取的DNS信息和前缀信息都设置无效标志，并包含在路由器通告报文中；将在绑定关系改变后从WAN连接获取的DNS信息和前缀信息包含在路由器通告报文中；在该桥端口上以组播形式发送路由器通告报文，发送设定次数(可配置，默认为2次)之后，从路由器通告报文中将在绑定关系改变前从WAN连接获取的DNS信息和前缀信息去掉，继续发送路由器通告报文。对DNS信息和前缀信息都设置无效标志，可以通过将DNS信息和前缀信息设置为0(二进制)来实现，以下无效标志的设置，也可以采用该方法，也可以采用其它方法。In the above step S101, when the WAN connection before and after the binding relationship is changed is a routing connection, the default routing time in the router advertisement message is the set time, and the source address is the address of the bridge; The DNS information and prefix information obtained from the WAN connection are all set with an invalid flag and included in the router advertisement message; the DNS information and prefix information obtained from the WAN connection after the binding relationship is changed are included in the router advertisement message; The router advertisement message is sent in multicast form on the bridge port. After sending the set number of times (configurable, the default is 2 times), the DNS information obtained from the WAN connection before the binding relationship is changed and the DNS information and The prefix information is removed, and the router advertisement message is continued to be sent. Setting the invalid flag for both the DNS information and the prefix information can be realized by setting the DNS information and the prefix information to 0 (binary). The setting of the following invalid flags can also use this method or other methods.

在上述步骤S101中，当绑定关系改变前WAN连接是路由连接，而绑定关系改变后WAN连接是桥接方式时，将在绑定关系改变前从WAN连接获取的DNS信息和前缀信息设置无效标志，缺省路由的时间设置为无效标志，并包含在路由器通告报文中。报文中含有一个字段lifetime，即缺省路由时间，0表示无效。当设备看到该字段不是0时，将报文的源地址取出来，作为缺省路由。源地址是桥的地址，在该桥端口上以组播形式发送路由器通告报文，发送设定次数(可配置，默认为2次)之后停止。In the above step S101, when the WAN connection is a routing connection before the binding relationship is changed, and the WAN connection is a bridge connection after the binding relationship is changed, the DNS information and prefix information obtained from the WAN connection before the binding relationship is changed are invalid. flag, the time of the default route is set to an invalid flag, and included in the router advertisement message. The message contains a field lifetime, which is the default routing time, and 0 means invalid. When the device sees that this field is not 0, it extracts the source address of the packet as the default route. The source address is the address of the bridge, and the router advertisement message is sent in multicast form on the bridge port, and stops after sending the set number of times (configurable, 2 times by default).
在上述步骤S101中，当绑定关系改变前后WAN连接都是桥接方式时，首先获取绑定关系改变前的WAN连接上监控到的路由器通告报文信息，该信息包括包括源地址、DNS信息以及前缀信息，根据这些信息，构造第一路由器通告报文，且将在绑定关系改变前从WAN连接获取的DNS信息、缺省路由时间和前缀信息设置无效标志，并包含在路由器通告报文中；在该桥端口上以组播形式发送路由器通告报文，发送设定次数(可配置，默认为2次)之后停止。In the above step S101, when the WAN connection before and after the binding relationship is changed is in the bridging mode, first obtain the router advertisement message information monitored on the WAN connection before the binding relationship is changed, the information includes source address, DNS information and Prefix information, based on these information, construct the first router advertisement message, and set the invalid flag on the DNS information, default routing time and prefix information obtained from the WAN connection before the binding relationship is changed, and include it in the router advertisement message ;Send router advertisement messages in multicast form on the bridge port, and stop after sending the set number of times (configurable, 2 times by default).
另外，家庭网关在桥上接收路由器请求报文，获取接收路由器请求报文的桥端口，当前绑定的WAN连接是路由连接时，在该桥端口以组播形式发送路由器通告报文进行回复；当前绑定的WAN连接是桥连接时，对该路由器请求报文不响应。器通告报文的源地址是桥的地址，报文中的DNS信息地址和前缀信息是在绑定关系改变后从WAN连接获取的DNS信息和前缀信息。In addition, the home gateway receives the router request message on the bridge, obtains the bridge port that receives the router request message, and when the currently bound WAN connection is a routing connection, sends a router notification message in multicast form on the bridge port to reply; When the currently bound WAN connection is a bridge connection, it does not respond to the router solicitation message.
