cisco PIX上配置PPPOE Client与PPPOE SERVER通信
思科cisco依靠自身的技术和对网络经济模式的深刻理解，使其成为了网络应用的成功实践者之一，那么你知道cisco PIX上配置PPPOE Client与PPPOE SERVER通信吗?下面是小编整理的一些关于cisco PIX上配置PPPOE Client与PPPOE SERVER通信的相关资料，供你参考。
cisco PIX上配置PPPOE Client与PPPOE SERVER通信：
拓扑图
1,说明
ü Cisco 1721来模拟PPPOE SERVER
üPIX501来模拟PPPOE Client
2,实验过程
配置CISCO 1721为PPPOE SERVER
//首先底层配置,这没什么说的，大家已经非常熟悉了~~
Router(config)#no ip domain-lookup
Router(config)#line console 0
Router(config-line)#exec-timeout 0 0
Router(config-line)#logg syn
Router(config-line)#host PPPOE_SERVER
PPPOE_SERVER(config)#int e0/0
PPPOE_SERVER(config-if)#ip add 192.168.0.1 255.255.255.0
PPPOE_SERVER(config-if)#no sh
PPPOE_SERVER(config-if)#pppoe enable //接口下开启PPPOE 会话功能
PPPOE_SERVER(config-if)#exit
PPPOE_SERVER(config)#vpdn enable //全局开启VPDN服务
PPPOE_SERVER(config)#vpdn-group PPPOE //创建VPDN拨号组，此处我设置的名称为PPPOE，注意这里创建的组名要和PIX上启用的VPDN组名要一致，不然pppoe session会话失败
PPPOE_SERVER(config-vpdn)#accept-dialin //接受拨号请求
PPPOE_SER(config-vpdn-acc-in)#protocol pppoe //指定会话协议为pppoe
PPPOE_SER(config-vpdn-acc-in)#virtual-template 1 //创建虚模板 1，表示第几个虚模板，创建虚模板之后，会立即看见Virtual-Access1, changed state to up
PPPOE_SER(config-vpdn-acc-in)#end
*Mar 1 00:06:27.707: %LINK-3-UPDOWN: Interface Virtual-Access1, changed state to up
*Mar 1 00:06:28.707: %LINEPROTO-5-UPDOWN: Line protocol on Interface Virtual-Access1, changed state to up
PPPOE_SERVER#conf t
Enter configuration commands, one per line. End with CNTL/Z.
PPPOE_SERVER(config)#int virtual-template 1 //进入虚模板1
PPPOE_SERVER(config-if)#ip unnumbered e0/0 //此处不要给虚模板配置IP地址，建议使用ip unnumbered 向物理接口E0/0借用，因为E0/0接口为outside接口，已开启pppoe enable
PPPOE_SERVER(config-if)#ppp authentication pap //指定ppp认证方式为pap，采用认证方式为PAP，认证过程会话用户名和密码为明文，你可以采用chap
PPPOE_SERVER(config-if)#peer default ip address pool ADSL //指定地址池的名称为ADSL，可以随意指定名称，但要和下面的地址池名称一致
PPPOE_SERVER(config-if)#exit
PPPOE_SERVER(config)#ip local pool ADSL 200.0.0.1 200.0.0.10 //指定地址池的地址范围，这个地址范围必须是连续的
PPPOE_SERVER(config)#username wangwanli password wangwanli //指定pppoe拨号的用户名和密码
PPPOE_SERVER(config)#end
到此PPPOE_SERVER上配置已全部完成
PIX上进行配置
pixfirewall> enable
Password:
pixfirewall#
pixfirewall# conf t
pixfirewall(config)# vpdn group PPPOE request dialout pppoe //指定vpdn会话名称PPPOE,这个名称与pppoe server上的VPDN组名是一致的
pixfirewall(config)# vpdn group PPPOE localname wangwanli //指定vpdn本地用户名
pixfirewall(config)# vpdn ?
configure mode commands/options:
group Keyword to specify a group name
username Keyword to configure username
pixfirewall(config)# vpdn group PPPOE ppp authentication pap //指定ppp认证方式为pap，与pppoe server认证方式一致
pixfirewall(config)# vpdn username wangwanli password wangwanli //指定拨号的用户名和密码
pixfirewall(config)# int e1
pixfirewall(config-if)# no sh //激活接口
pixfirewall(config-if)# nameif outside //定义接口为outside，默认的安全级别为0
INFO: Security level for "outside" set to 0 by default.
pixfirewall(config-if)# ip address pppoe setroute //从pppoe 服务器获得IP地址
pixfirewall(config-if)# end
到此PIX上的配置已经完成，如下是调试现象
pixfirewall# debug ppp auth //打开ppp 认证调试
pixfirewall# debug pppoe event //打开pppoe 拨号事件请求
debug pppoe event enabled at level 1
pixfirewall# show ip address outside ?
dhcp Show DHCP lease information
pppoe Show PPPoE interface information

pixfirewall# show ip address outside pppoe
//PIX上完成拨号之后，查看得到的IP地址

现在我把PIX上的E1接口重新关闭之后，再打开，再来观察一下PIX上的pppoe 的会话过程与PPPOE SERVER上的看到的pppoe 会话的四个过程，PADI---PADO-PADR-PADS 四个过程

到这里PIX上的pppoe 会话已经结束，已经得到从PPPOE SERVER上分配的地址
PPPOE SERVER上开启debug之后，收到PIX上的PPPOE 会话请求
