Juniper SRX防火墙 基本配置手册
1 SRX防火墙的PPPoE拔号配置
Juniper SRX防火墙支持PPPoE拔号,这样防火墙能够连接ADSL链路,提供给内网用户访问网络的需求。
配置拓扑如下所示:
Ge-0/0/4 via PPPoE to obtian IP addressJuniper SRX240防火墙
在Juniper SRX防火墙上面设置ADSL PPPoE拔号,可以在WEB界面或者命令行下面查看PPPoE拔号接口pp0,在命令行下面的查看命令如下所示:
juniper@HaoPeng# run show interfaces terse | match pp
Interface Admin Link Proto Local Remote pp0 up up
在WEB界面下,也能够看到PPPoE的拔号接口pp0
配置步聚如下所示:
第一步:选择接口ge-0/0/4作为PPPoE拔号接口的物理接口,将接口封装成PPPoE To configure PPPoE encapsulation on an Ethernet interface:
juniper@HaoPeng# set interfaces ge-0/0/4 unit 0 encapsulation ppp-over-ether
第二步:配置PPPoE接口PP0.0的参数
To create a PPPoE interface and configure PPPoE options:
user@host# set interfaces pp0 unit 0 pppoe-options underlying-interface ge-0/0/4.0 auto-reconnect 100 idle-timeout 100 client
第三步:配置PPPoE接口的MTU值
To configure the maximum transmission unit (MTU) of the IPv4 family: user@host# set interfaces pp0 unit 0 family inet mtu 1492
第四步:配置PPPoE接口的地址为negotiate-address
To configure the PPPoE interface address:
user@host# set interfaces pp0 unit 0 family inet negotiate-address
第五步:配置PPPoE接口的PAP认证
set int pp0 unit 0 ppp-options pap default password 88888878 local-name szdigicn1@163.gd local-password 88888878 passive 注意:default password和local password都必须设置成ADSL拔号时所用的密码,local name必须是ADSL拔号时所用的用户名。
第六步:配置静态路由指向PPOE接口PP0.0
set routing-options static route 0.0.0.0/0 next-hop pp0.0
PPPoE拔号配置输出汇总如下所示: set interfaces ge-0/0/4 unit 0 encapsulation ppp-over-ether set interfaces pp0 unit 0 ppp-options pap default-password 88888878 set interfaces pp0 unit 0 ppp-options pap local-name \ set interfaces pp0 unit 0 ppp-options pap local-password 88888878 set interfaces pp0 unit 0 ppp-options pap passive set interfaces pp0 unit 0 pppoe-options underlying-interface ge-0/0/4.0 set interfaces pp0 unit 0 pppoe-options idle-timeout 0 set interfaces pp0 unit 0 pppoe-options auto-reconnect 2 set interfaces pp0 unit 0 pppoe-options client set interfaces pp0 unit 0 family inet mtu 1492 set interfaces pp0 unit 0 family inet negotiate-address set routing-options static route 0.0.0.0/0 next-hop pp0.0 验证PPPoE是否已经拔通,已经获得IP地址
root# run show interfaces terse | match pp pp0 up up
pp0.0 up up inet 219.134.120.126 --> 219.134.120.1
验证PPPoE常见命令如下所示: show interfaces pp0 show pppoe interfaces show pppoe version show pppoe statistics clear pppoe sessions clear pppoe sta
