小公司常用的PPPOE撥號上網配置

拓撲圖

1.在企業路由器AR2上配置虛擬撥號口

system-view

[Huawei] sysname AR2

[AR2] dialer-rule

[AR2-dialer-rule] dialer-rule 1 ip permit

[AR2-dialer-rule] quit

[AR2] interface dialer 1

[AR2-Dialer1] dialer user XXX //user名稱

[AR2-Dialer1] dialer-group 1

[AR2-Dialer1] dialer bundle 1

[AR2-Dialer1] dialer timer idle 300

INFO: The configuration will become effective after link reset.

[AR2-Dialer1] dialer queue-length 8

[AR2-Dialer1] ppp chap user XXX //XXX指的是用戶名

[AR2-Dialer1] ppp chap password cipher XXX //XXX指的是密碼

[AR2-Dialer1] ip address ppp-negotiate

[AR2-Dialer1] quit

2.AR2和運營商路由器AR3建立建立PPPoE會話

[AR2] interface gigabitethernet 0/0/0

[AR2-GigabitEthernet1/0/0] pppoe-client dial-bundle-number 1 on-demand //注意這裡的1要和第一步的撥號口 1對應

[AR2-GigabitEthernet1/0/0] quit

3.AR2上配置路由器的靜態路由

ip route-static 0.0.0.0 0 dialer 1 //配置默認路由，下一跳指向撥號口1

4.在AR2撥號口上配置Easy IP方式的NAT Outbound

[AR2] acl 2000

[AR2-acl-basic-2000] rule 5 permit source 192.168.0.0 0.0.0.255

[AR2-acl-basic-2000] quit

[AR2] interface dialer 1

[AR2-Dialer1] nat outbound 2000

[AR2-Dialer1] quit
