基于默认路由器优先级的IPv6路由备份机制研究

随着互联网技术的爆炸性发展,网络应用日益深入到人们的生活之中。网络冗余备份机制显得越发重要。作为IPv4的替代协议,IPv6网络必须提供可靠的网络冗余机制保证业务的可靠传输。多路由器备份是一个日益重要的网络冗余备份机制。在多路由器备份场景中,在同一链路上的两个或多个路由器提供网络的冗余备份功能。本文中将分析研究IPv6邻居发现协议以及默认路由优先级协议,并利用路由器发现机制,邻居不可达检测机制以及默认路由器优先级实现网络冗余机制。

The Study of IPv6 Route Redundancy based on Default Route Preference

With the explosive growth of Intemet, the usage of Intemet increasingly comes into people＇s life. At the same time, network redundancy mechanism is more and more important. As a replacement of IPv4 protocol, IPv6 network need also to provide the network redundancy to make sure the successful transmission of service. Multiple routers redundancy is one important network redundancy scenario in which there are two or more routers on the same link to provide the network redundancy, in this paper, IPv6 neighbor discovery protocol and default router preference protocol will be analyzed and finally we will use the router discovery process, neighbor unreachable detection process and default router preference to implement the multiple routers redundancy scenario.
