目前,各企业网络上的路由器中流过的信息量越来越大。如何防止由于这些路由器的故障而带来网络的瘫痪,已经成为一个重要的、令人关注的问题。因此有关方面已经采取了一些行动来提供路由器故障后的补救处理手段。国际互联网络工程特别行动组(Internet EngineeringTask Force,简称IETF)最近刚刚发布了VRRP(VirtualRouter Redundancy Protocol,虚拟路由器冗余协议)的草案。该协议将在主路由器发生故障的时候为信息包的传递 At present, the amount of information flowing through the routers on the enterprise networks is getting larger and larger. How to prevent the network from being paralyzed due to the failure of these routers has become an important and concern issue. So the parties concerned have taken some actions to provide a remedy for the router after the failure. The Internet Engineering Task Force (IETF) recently released a draft of the Virtual Router Redundancy Protocol (VRRP). This protocol will deliver packets when the primary router fails
