Juniper_JUNOS8.5模拟器+逻辑路由器+RSVP配置说明

来源：华佗小知识

安装

Junos成功瘦身，117M，解压缩后149M。内置组播补丁，组播固化补丁，支持Vlan-tagging，支持Jweb 支持逻辑路由器

支持十个千兆网卡，这下可以搭出非常复杂的拓扑了！支持FreeBSD下的操作。

经本人试验，可稳定运行，启动与关机均只需一分钟。

系统运行后，可直接在虚拟机里操作，或者通过SecureCRT 来Telnet登陆，

同时支持串口登陆，压缩包内含pipe proxy，

NPTP：

其作用有点类似于部门使用的串口服务器，它把设备的串口和一个（IP+端口）对映射在一起，我们只用telnet这个ip的对应端口，就可以获得相当于访问该设备串口的服务。

按下图建立一个串口和（IP+端口）对的映射就可以了。

在建立好上面的映射关系后，保持NPTP软件始终打开就行。

JUNOS管理口为em0，其IP地址为192.168.1.254，对应的是虚拟机的第一块网卡Ethernet，在虚拟机属性里，正确选择这块网卡对应的主机虚拟网卡，并将这块虚拟网卡的IP地址设置为192.168.1.1，则不但可以适用JWeb，而且JUNOS可以联通。

帐号和JUNOS配置模式

系统账号：root 密码：juniper123 用户账号：mengmeng 密码：test123

系统环境： VMware-6.0 Freebsd 6.1

jinstall-8.5R1.14-domestic-signed jweb-8.5R1.14-signed

系统运行后，自动支持组播，

支持web访问，地址：http://192.168.1.254

支持Telnet 访问，地址：192.168.1.254 端口号：23

JUNOS的配置模式：按我的理解JUNOS有三种模式 @%

操作系统模式，处于FreeBSD操作系统，可以使用常用的FreeBSD相关命令，比如ls、pwd、cd等等，通过命令cli可以进入用户模式； >

用户模式，经过JUNOS封装的系统，可以进行一些简单的命令配置和所有信息显示，类似于我司路由器的config t之前的模式，使用configure命令可以进入配置模式； #

配置模式，在此模式下对路由器进行配置，类似于我司路由器的config t之后的模式。

JUNOS的命令风格：

JUNOS的命令风格在业界很特别，仅与Alcatel的命令风格略有相似之处。这里只作简单的介绍，具体的使用希望大家钻研。

JUNOS采用edit、set、delete、show、run show和commit来完成主体功能的配置。值得注意的是，在完成了某项功能的配置之后，只有使用commit命令提交成功之后，该配置才会生效，在commit提交之后，系统会对提交的配置进行合法性检查，只有通过合法性检查才算提交成功，否则系统会给出错误信息。合法性检查仅检查配置的合法性，并不检查配置的准确性与正确性，请注意。

里面已经配置了OSPF协议，可以完美运行。拓扑图如下：

RSVP配置

RSVP功能主要从interfaces、protocols和routing-options三个方面进行配置。

Interfaces

初始时，interface视图下是没有什么配置的，但是我们可以通过(run) show interfaces terse命令看到有em0到em3四个网口，这就是我们虚拟机里看到的四个intel千兆网卡。

这样，我们需要给对应的网卡和lo0配上需要的ip地址。完成如下的配置即可

当完成了上述配置之后再显示接口信息会如下图。

值得注意的是，进行TE的相关配置时，物理接口必须支持mpls协议族，即family mpls。同时给物理接口配置了地址之后，可能使用上面的命令看不到具体的地址信息，并且也ping不通对端接口，这是正常的，应该是模拟器的原因，这时候需要保存一下配置，重启模拟器，就正常了。

Protocols

Protocol视图下，需要编辑三个对应的子视图，rsvp子视图、mpls子视图和ospf子视图（视具体选用的igp而定）。

Rsvp子视图的配置如下：

在子视图下添加rsvp接口，即使能对应接口的rsvp功能即可，这类似于我司设备在物理接口下使能te功能和设置带宽参数。 Mpls子视图的配置如下：

在该视图下，首先也要添加mpls接口，其次在te隧道和其路径的配置都在该视图下进行，上图中的lsp和path分别对应te隧道和显示路径，其他的一些属性配置整个业界大致都是一致的，仔细找下具体的命令即可，这里主要描述一个配置框架，不对细节太过于描述。

Ospf子视图的配置如下：

在子视图下添加ospf接口，并配置ospf支持te，与我司设备配置一致。这里需要注意的是，由于模拟器的原因，ospf不能支持组播，所以需要将ospf接口类型设置为nbma，并且显示指定ospf邻居，才能触发ospf发送单播的协议报文，建立ospf邻居，还有哪些方式可以实现同样的功能，个人没有去探究，因为在这里重点关注的是te而非ospf，望谅。
