作为一名网工，以前一直在51CTO上向前辈学习，今天我也试着写个小实验，第一次写，大部都是命令，记录自己的操作，也希望可以给别人带来帮助，谢谢。
一、拓扑图
二、实现环境
拓扑图中为四台vmx路由，两台作为PE设备，两台作为CE设备；
PE设备的软件版本Junos: 18.1R1.9，CE设备的软件版本为：Junos: 14.1R1.10
CE1配置了两个vlan2100、vlan2200
CE2配置了两个vlan2100、vlan2200
CE1：vlan2100 192.168.10.10/24 gateway 192.168.10.254
CE1: vlan2200 192.168.20.10/24 gateway 192.168.20.254
CE2: vlan2100 192.168.10.20/24 gateway 192.168.10.254
CE2: vlan2200 192.168.20.20/24 gateway 192.168.20.254
目的：CE1与CE2之间的IP地址三层可达
CE1可以ping通 192.168.10.20、192.168.20.20
CE2可以ping通 192.168.10.10、192.168.20.10
三、配置步骤
1、配置PE与PE之间互联IP地址
root@PE1# show interfaces | display set
set interfaces ge-0/0/0 unit 0 family inet address 10.0.12.1/24
set interfaces ge-0/0/0 unit 0 family mpls
set interfaces ge-0/0/1 unit 0 family inet address 10.0.21.1/24
set interfaces ge-0/0/1 unit 0 family mpls
set interfaces lo0 unit 0 family inet address 1.1.1.1/32
root@PE2# show interfaces | display set
set interfaces ge-0/0/0 unit 0 family inet address 10.0.12.2/24
set interfaces ge-0/0/0 unit 0 family mpls
set interfaces ge-0/0/1 unit 0 family inet address 10.0.21.2/24
set interfaces ge-0/0/1 unit 0 family mpls
set interfaces lo0 unit 0 family inet address 2.2.2.2/32
2、配置OSPF协议，lo0接口三层可达
root@PE1# show protocols ospf | display set
set protocols ospf area 0.0.0.0 interface lo0.0 passive
set protocols ospf area 0.0.0.0 interface ge-0/0/0.0
set protocols ospf area 0.0.0.0 interface ge-0/0/1.0
root@PE2# show protocols ospf | display set
set protocols ospf area 0.0.0.0 interface lo0.0 passive
set protocols ospf area 0.0.0.0 interface ge-0/0/0.0
set protocols ospf area 0.0.0.0 interface ge-0/0/1.0
[edit]
root@PE1# run ping 2.2.2.2 source 1.1.1.1
PING 2.2.2.2 (2.2.2.2): 56 data bytes
64 bytes from 2.2.2.2: icmp_seq=0 ttl=64 time=216.467 ms
64 bytes from 2.2.2.2: icmp_seq=1 ttl=64 time=46.884 ms
^C
--- 2.2.2.2 ping statistics ---
2 packets transmitted, 2 packets received, 0% packet loss
round-trip min/avg/max/stddev = 46.884/131.675/216.467/84.792 ms
3、配置MPLS、LDP协议，支持label转换

set protocols mpls interface all
[edit]
root@PE1# show protocols ldp | display set
set protocols ldp interface all

4、在两台PE之间配置MP-BGP，传输E×××信令
[edit]
root@PE1# show routing-options | display set
set routing-options router-id 1.1.1.1
set routing-options autonomous-system 65000
set routing-options forwarding-table export load-blance
