Juniper VMX路由器实现逻辑系统互通
1、通过SecureCRT的方式SSH登录到VMX路由器，在登录路由器之前，需要开启SSH服务、及配置接口的IP地址服务。如下所示：
[edit]
root@JNCIP-Lab# show system services | display set
set system services ftp
set system services ssh
set system services telnet connection-limit 5
[edit]
root@JNCIP-Lab# show interfaces | display set
set interfaces ge-0/0/0 unit 0 family inet address 192.168.136.15/24
记得通过VmwareWorkstation的虚拟网卡关联到VMX的网卡。
2、从电脑端测试Ping，是否可以到达VMX路由器：
3、打开SecureCRT登录界面，登录到VMX路由器
4、使用Root帐号登录时，显示的是%层次，如下所示：
root@JNCIP-Lab%
root@JNCIP-Lab%
进入到配置模式：
root@JNCIP-Lab> configure
Entering configuration mode
[edit]
root@JNCIP-Lab#
5、配置两个逻辑系统r1和r2，在配置以下配置之前，需要在全局的启用两个接口ge-0/0/1, ge-0/0/2的vlan-tagging
root@JNCIP-Lab# show interfaces | display set
set interfaces ge-0/0/0 unit 0 family inet address 192.168.136.15/24
set interfaces ge-0/0/1 vlan-tagging
set interfaces ge-0/0/2 vlan-tagging
同时，虚拟网卡的在Vmware Workstation也需要绑定到同一个虚拟网卡：
root@JNCIP-Lab# show logical-systems r1 | display set
set logical-systems r1 interfaces ge-0/0/1 unit 12 description r2ge-0/0/2.12
set logical-systems r1 interfaces ge-0/0/1 unit 12 vlan-id 12
set logical-systems r1 interfaces ge-0/0/1 unit 12 family inet address 10.0.4.5/30
[edit]
root@JNCIP-Lab# show logical-systems r2 | display set
set logical-systems r2 interfaces ge-0/0/2 unit 12 description r1ge-0/0/1.12
set logical-systems r2 interfaces ge-0/0/2 unit 12 vlan-id 12
set logical-systems r2 interfaces ge-0/0/2 unit 12 family inet address 10.0.4.6/30
6、现在单独的登录到r1和r2进行Ping的测试：
root@JNCIP-Lab% cli
root@JNCIP-Lab> set cli logical-system r1
Logical system: r1
root@JNCIP-Lab:r1>
root@JNCIP-Lab% cli
root@JNCIP-Lab> set cli logical-system r2
Logical system: r2
root@JNCIP-Lab:r2>
root@JNCIP-Lab:r1> ping 10.0.4.6 count 5 rapid
PING 10.0.4.6 (10.0.4.6): 56 data bytes
!!!!!
--- 10.0.4.6 ping statistics ---
5 packets transmitted, 5 packets received, 0% packet loss
round-trip min/avg/max/stddev = 2.404/4.491/6.835/1.473 ms
root@JNCIP-Lab:r2> show arp
