RIP uses a modified hop count to determine network distance. A modified hop count reflects how network engineers can assign paths a higher cost -- as if they involved extra hops -- if they want to limit or disc
本文档介绍 Routing Information Protocol 版本 2 (RIPv2) 路由信息交换进程身份验证的配置示例。
Routing Information Protocol (RIP) is a distance-vector routing protocol. Routers running the distance-vector protocol send all or a portion of their routing tables in routing-update messages to their neighbors.
Routing Information Protocol (RIP) is disabled by default on the switch. Thenoshutdown (RIP)command in router-RIP configuration mode will enable RIP. Example This command enables RIP on the switch. switch(config-router-rip)#no shutdownswitch(config-router-rip)# ...
RIP协议采用距离向量算法,在实际使用中已经较少适用。在默认情况下,RIP使用一种非常简单的度量制度:距离就是通往目的站点所需经过的链路数,取值为0~16,数值16表示路径无限长。RIP进程使用 UDP 的520端口来发送和接收RIP分组。RIP分组每隔30s以广播的形式发送一次,为了防止出现“广播风暴”,其后续的分组将做随机延时后...
The details depend upon the speci c protocol. As an example, in RIP every gateway that participates in routing sends an update message to all its neighbors once every 30 seconds. Suppose the current route for network N uses gateway G. If we don't hear from G for 180 seconds, we can ...
命令rip metricout用于路由器在通告RIP路由时修改路由的度量值。 RIPv2 RIPv2 报文结构 RIPv2的报文格式的基本结构和RIPv1相同。RIPv2使用了RIPv1中部分未用字段以提供扩展功能。 报文格式部分字段解释如下: 【Route Tag】:用于标记外部路由或者路由引入到RIPv2协议中的路由。
The following figure shows an example of a network running the RIP routing protocol. In this network, the router A has three routes to the destination network. These routes are the following. The four-hops route(distance)through routerB(vector) ...
RIP:路由信息协议RIP(Routing Information Protocol)的简称,它是一种基于距离矢量(Distance-Vector)算法的协议,使用跳数作为度量来衡量到达目的网络的距离。RIP主要应用于规模较小的网络中。古老,收敛速度很慢! R1: rip 1 启动rip进程1 version 2 指定使用版本2 ...
RIP(Routing Information Protocol) 路由协议框架 1. RIPv1(RFC 1058) RIP 从 Xerox 开发的早期协议 -网关信息协议 (GWINFO)演变而来。随着 Xerox 网络系统 (XNS) 的发展,GWINFO 逐渐演变成 RIP。此后,由于 Berkeley 软件分发 (BSD) 的 routed(读作“route-dee”,而不是“rout-ed”)守护程序中采用了 RIP,...
