Juniper路由器入门之一：需要子接口的端口配置

set interfaces fe-2/0/1
vlan-tagging             
――――在配置接口启用封装VLAN

set interfaces fe-2/0/1 unit 424 vlan-id
424      
―――――配置子接口，VLAN 424

set interfaces fe-2/0/1 unit 424 family inet address
192.168.254.146/30  ――配置子接口地址

Juniper路由器入门之二：无需子接口配置

set interfaces fe-2/0/23 unit 0 family inet address
222.60.11.154/29   ――直接配置地址

Juniper路由器入门之三：E1口配置

set interfaces e1-3/0/0 encapsulation ppp
封装链路类型，包含PPP,HDLC，根据实际情况配置

set interfaces e1-3/0/0 e1-options framing unframed
封装帧格式，参数包含unframed,g704, g704-no-crc4

set interfaces e1-3/0/0 unit 0 family inet address 192.168.1.126/30
配置地址

Juniper路由器入门之四：CE1配置

set interfaces ce1-4/0/0 clocking external

set interfaces ce1-4/0/0 e1-options framing g704-no-crc4

set interfaces ce1-4/0/0 partition 1 timeslots
1-31   
――――设置信道1及时隙1－31

set interfaces ce1-4/0/0 partition 1 interface-type
ds  ――――子接口类型DS

set interfaces ds-4/0/0:1 encapsulation
ppp        
―――――配置子接口封装ppp

set interfaces ds-4/0/0:1 unit 0 family inet filter input NYYH

set interfaces ds-4/0/0:1 unit 0 family inet address
10.238.173.197/30  ――――配置地址

Juniper路由器入门之五：策略配置

set firewall filter shigonganjuMAS term 1 from source-address
10.238.173.180/30

set firewall filter shigonganjuMAS term 1 then accept

set firewall filter shigonganjuMAS term 2 from source-address
10.238.173.0/24

set firewall filter shigonganjuMAS term 2 from source-address
10.238.179.0/24

set firewall filter shigonganjuMAS term 2 then discard

set firewall filter shigonganjuMAS term 3 then accept

set interfaces fe-2/0/0 unit 44 family inet filter input
