JUNIPER MX PPPOE拨号实验2.0-yubj314的博客
'''
上次的实验并没有搞定radius服务器，所以采用的是本地认证。
这次使用single vlan 动态配置文件。
这次的实验是PPP over PPPOE over dynamic single VLAN over Ethernet。
'''
实验拓扑：
实验配置：
1.pppoe接口的动态配置文件：
dynamic-profiles {
basic-pppoe-profile {
interfaces {
pp0 {
unit "$junos-interface-unit" {
ppp-options {
pap; #pap或者chap
}
pppoe-options {
underlying-interface "$junos-underlying-interface";
server; #必填。
}
family inet {
unnumbered-address lo0.0;
}
}
}
}
}
2.单vlan的动态配置文件：
autovlan {
interfaces {
"$junos-interface-ifd-name" { #IFD
unit "$junos-interface-unit" { #IFL
vlan-id "$junos-vlan-id";
family pppoe { #IFF
access-concentrator test;
dynamic-profile basic-pppoe-profile;
}
}
}
}
3.接口的配置：
ge-0/0/2 {
flexible-vlan-tagging; #开启vlan-tagging
auto-configure { #在该接口上动态产生vlan
vlan-ranges {
dynamic-profile autovlan {
accept any; #允许PADX包来触建立vlan
ranges {
any; #允许的vlan
}
}
}
}
}
lo0 {
unit 0 {
family inet {
address 10.11.11.1/32;
}
}
}
}
4.radius的配置：
access {
radius-server { #定义radius-server组
192.168.111.130 {
port 1812;
accounting-port 1813;
secret "$9$YlgZUik.5z3HkO1Ecle"; ## SECRET-DATA
source-address 192.168.111.129;
}
}
group-profile DNS {
ppp {
primary-dns 114.114.114.114;
}
}
profile radius {
accounting-order radius;
authentication-order radius;
radius {
authentication-server 192.168.111.130; #调用radius server
accounting-server 192.168.111.130;
}
}
5.验证用户：

6.查看接口的traffic：

04:43:15.478879 In PPPoE PADR [Service-Name] [Host-Uniq UTF8] [AC-Cookie UTF8] #client端的单播Reques报文
在和动态配置文件关联的基础接口上，收到PADR报文之后，创建动态的pppoe逻辑接口。
server发出PPPOE的PADS确认PPPOE连接的确认。

Use <no-resolve> to avoid reverse lookups on IP addresses. #剩下的一些我也看不太懂 但是整个过程还需要NCP来完成ip的提供和路由的安装。
