實驗步驟:spa

1.配置地址池:server

root# show access   blog

profile none {接口

    authentication-order none;    此次實驗沒有radius認證it

}io

address-assignment {class

    pool addtest {test

        family inet {

            network 192.168.11.0/24;

            range 1 {

                low 192.168.11.10;

                high 192.168.11.250;

            }

        }

    }

}

2.配置動態pppoe配置文件:

pppoe {

    interfaces {

        pp0 {

            unit "$junos-interface-unit" {

                ppp-options {

                    pap;

                }

                pppoe-options {

                    underlying-interface "$junos-underlying-interface";

                    server;

                }

                family inet {

                    unnumbered-address lo0.0;

                }

            }

        }

    }

}

在pp0接口下關聯物理接口,而且做爲pppoe的服務器端。

區別於靜態配置,$junos這個變量在這裏充當了佔位符。

$junos-underlying-interface佔位符是收到數據包的地方,好比ge-1/0/0。

$junos-interface-unit 是單元的佔位符,JUNOS OS在給數據包動態分配UNIT時候自動配置


3.接口調用PPPOE的配置:

root# show interfaces

ge-0/0/0 {

    unit 0 {

        family pppoe {

            access-concentrator mx104-test;

            duplicate-protection;

            dynamic-profile pppoe;

        }

    }

}

4.PC撥號:

在MX上檢查用戶:

[edit]

root# run show subscribers

Interface           IP Address/VLAN ID            User Name                      LS:RI

pp0.1073741863      192.168.11.12                 1111                      default:default
