热备份路由协议允许IP网络在一个路由器失效时,由网络中的另一个路由器自动接替失效路由器的工作,从而实现IP路由容错。本文介绍了热备份路由协议的组成,阐述了其工作原理和操作中的注意事项。
Hot backup routing protocol allows the IP network in the event of a router failure, another router in the network automatically take over the failure of the router’s work in order to achieve IP routing fault tolerance. This article describes the composition of the hot backup routing protocol, describes its working principle and operation considerations.
