1、H3C路由学习笔记静态路由H3C路由（MSR26-30）1、进入系统视图Startup configuration file does not exist.Performing automatic configuration. Press CTRL_D to break.-按Ctrl + D键终止设备查找自动配置Automatic configuration attempt: 1.Not ready for automatic configuration: no interface available.Waiting for the next.Automatic configuration i

2、s aborted.-按Ctrl + D键后放弃自动配置的尝试Line aux0 is available.Press ENTER to get started.-到这里系统启动完毕，按回车键%Aug 22 09:19:53:318 2014 H3C SHELL/5/SHELL_LOGIN: TTY logged in from aux0.-再按一次回车键 system-viewH3C2、修改路由器名称sysH3Csysname 名称如将默认的路由器名称改为RoNetwork_Dept，Ro表示设备类型为路由器，Network_Dept表示部门名称，以后看到这个名称就知道这是什么设备、在什么位

3、置。建议以后都采用这种方式来给设备命名，以方便管理。H3Csysname RoNetwork_DeptRoNetwork_Dept如果要恢复默认名称，使用undo sysname命令：RoNetwork_Deptundo sysnameH3C3、显示路由表（1）IPv4显示路由表概要信息：RoNetwork_Deptdisplay ip routing-table显示路由表详细信息：RoNetwork_Deptdisplay ip routing-table verbose显示某种路由协议的信息：RoNetwork_Deptdisplay ip routing-table protocol b

4、gp|direct|guard|isis|ospf|rip|static还有其他信息，可使用？显示帮助以便选择：RoNetwork_Deptdisplay ip routing-table ?（2）IPv6只需将IPv4的命令中ip替换成ipv6即可。4、配置接口sys system-viewH3Cint 接口名称如配置G0/0接口：RoNetwork_Deptint g0/0RoNetwork_Dept-GigabitEthernet0/0-进入接口配置视图配置IP地址：RoNetwork_Dept-GigabitEthernet0/0ip add ?-后面跟掩码长度也行，跟掩码也行 INT

5、EGER IP mask length IP maskRoNetwork_Dept-GigabitEthernet0/0ip add 24 -24表示掩码长度为24位，和RoNetwork_Dept-GigabitEthernet0/0undo shutdown-激活接口RoNetwork_Dept-GigabitEthernet0/0dis int g0/0-查看接口信息5、信息回显及tracert为了防止命令被系统输出的消息打断，可以配置信息回显：RoNetwork_Deptinfo-center synchronous为防止tracert超时，链路两端的设备都要开启以下功能：RoNetw

6、ork_Deptip redirects enable 开启设备的ICMP重定向报文的发送功能RoNetwork_Deptip ttl-expires enable开启设备的ICMP超时报文的发送功能RoNetwork_Deptip unreachable enable 开启设备的ICMP目的不可达报文的发送功能6、配置静态路由拓扑图：RoNetwork_Dept端：sysSystem View: return to User View with Ctrl+Z.H3Csys RoNetwork_DeptRoNetwork_Deptinfo syncInfo-center synchronous
