Juniper--Juniper的基本配置.doc

Juniper-Juniper的基本配置(献给要学juniper的同学)本专题所有Juniper的配置环境均为qemu+free bsd 4.8 mini+JUNOS Base OS boot 7.2R4.2+4块虚拟出来的tap网卡,由于Juniper的路由器支持传统意义的VR-VPN，也就是可以把一个路由器当成多个路由器来用（16个），所以用一个路由器也可以完成多个路由器的互连。Juniper的基本配置：root# cli#相当于cisco的enrootcli configure#相当于cisco的configure terminaleditroot# set system host-name router1#配置路由器的名字为router1root# set system domain-name #配置路由器所在域为root# set interfaces fxp0 unit 0 family inet address /24#配置fxp0 unit 0的接口地址，fxp0代表管理接口，unit 0代表子接口,inet代表是ipv4地址。root# set system backup-router #backup-router是本路由器的直连路由器，在路由器启动的时候，#JUNOS路由软件(routing protocol process, RPD)没有立即启动，#路由器将自动生成一条到back-up router的缺省路由，当路由器启动完成后再自动删除这条路由。root# set system name-server #DNS的地址root# set system root-authentication plain-text-password#设置明文密码New password:Retype password:#输入并且确认密码，要求字母和数字。root# commit#确认配置，在没有确认配置的时候所有配置都是不生效的！rootrouter1# exitrootrouter1#保存配置用save命令editavivarouter1# save configuration-march02Wrote 433 lines of configuration to configuration-march02#察看保存过的文件用run file list命令avivarouter1# run file list/var/home/aviva:.ssh/configuration-march02#用保存的文件载入配置用load replace命令。load replace XXXJunOS的show命令在configure模式下可以用show命令查看当前视图下的配置，Juniper有多种视图在命令前面的方括号里面能看到所在的视图名称：确省视图为system视图，如下，只有edit显示在上面editrootstim# showversion 7.2R4.2;system host-name stim;domain-name ;syslog user * any emergency;file messages any notice;authorization info;file interactive-commands interactive-commands any;interfaces fxp0 unit 0 family inet address /24;下面一种是interface视图，不同视图下，用show命令show出来的结果是不一样的。edit interfacesrootstim# showfxp0 unit 0 family inet address /24;下面要介绍的命令是show | display set,这个命令能够查看在该视图下曾经做过一些什么操作。edit interfacesrootstimRouterA# show | display setset interfaces fe-0/0/1 unit 0 family inet address /24set interfaces se-0/0/2 unit 0 family inet address /24set interfaces se-0/0/3 serial-options clocking-mode dceset interfaces se-0/0/3 unit 0 family inet address /24set interfaces lo0 unit 0 family inet address /32用show compare命令查看配置过的脚本rootstim# edit system servicesedit system servicesrootstim# set telnetedit system servicesrootstim# exiteditrootstim# exitThe configuration has been changed but not committedExit with uncommitted changes? yes,no (yes) norootstim# show | compareedit system+ services + telnet;+ JunOS其他常用操作：无论做什么操作的时候Juniper都需要通过commit命令使配置生效，这点和cisco huawei不是很一样，cisco huawei的做法是配置上去立即生效。用commit check查看配置是否正确，如图在commit check的时候发生报错，需要修改。editrootstimrouter1# commit checkedit protocols rip group alpha-rip-groupneighbor fe-0/0/0.0Failed to configure neighbor fe-0/0/0.0: already in group alpha-rip-grouperror: configuration check-out failed每次我们想commit配置的时候都需要退出到cli界面，需要打多个quit命令，这里介绍一个直接的办法，如果想保存配置并且回到用户视图下可以用commit and-quitedit protocols ospfrootstim# edit area 0edit protocols ospf area rootstim# commit and-quit用top命令直接回到system视图下edit protocols ospfrootstim# topeditrootstim# edit protocols ospfedit protocols ospfrootstim# edit area 0edit protocols ospf area rootstim# topeditrootstim#如果配置出问题需要回滚配置的时候可以用rollback命令。rootstim# rollback ?Possible completions: Execute this command0 2007-09-30 13:58:53 UTC by root via cli1 2007-09-30 13:42:55 UTC by root via cli2 2007-09-28 15:47:34 UTC by root via cli3 2007-09-28 15:47:16 UTC by root via cli4 2007-09-28 15:46:44 UTC by root via cli5 2007-09-28 00:54:45 UTC by root via other| Pipe through a commandedit查看当前版本：rootstim show versionHostname: stimModel: oliveJUNOS Base OS boot 7.2R4.2JUNOS Base OS Software Suite 7.2R4.2JUNOS Ker
