要实现远程路由器治理: (config)# int asy 5 (config-if)# en ppp (config-if)# asyn mode dedicated
对远程用户分配IP地址: (config)# int asy 5 (config-if)# peer default ip address 192.168.10.2
需要对拨号用户使用地址池,可以这样: (config)# ip local pool wolf 192.168.0.50 192.168.0.254 (config)# int asy 5 (config-if)# peer default ip address pool wolf
不过好象要重启路由器才有效!
Building configuration... version 12.1 service timestamps debug uptime service timestamps log uptime no service password-encryption ! hostname Router ! enable password cisco ! memory-size iomem 25 ip subnet-zero ip host modem 2005 1.1.1.1 ! interface Loopback0 ip address 1.1.1.1 255.255.255.0 ! interface Serial0 no ip address shutdown ! interface FastEthernet0 no ip address shutdown speed auto ! interface Async5 ip address 192.168.0.1 255.255.255.0 encapsulation ppp 这个一定要!不然看到的是乱码! async mode dedicated 一定要!若改成async mode inter,对方拨号时总是停在检验用户名和密码那里!若两个都不设,拨号不上! peer default ip address 192.168.0.2 ! ip classless no ip http server ! line con 0 transport input none line aux 0 password cisco login modem InOut transport input all stopbits 1 speed 115200 flowcontrol hardware line vty 0 4 login ! no scheduler allocate end
以上配置的效果就是:对方拨号,不需要用户名和密码,连结成功,就和拨96169一样!
要让拨号用户加上认证可以这样做: (config)# username wolf password igpwwk (config)# int asy 5 (config-if)# ppp au pap 也可以使用chap认证: (config-if)# ppp au chap 或者同时使用: (config-if)# ppp au chap ppp (config-if)# ppp au ppp chap
以下是将串口模拟成异步口: Building configuration... version 12.1 service timestamps debug uptime service timestamps log uptime no service password-encryption ! hostname Router ! enable password cisco ! username wolf password 0 igpwwk ! memory-size iomem 25 ip subnet-zero ip host modem 2001 1.1.1.1 ! interface Loopback0 ip address 1.1.1.1 255.255.255.0 ! interface Serial0 physical-layer async ip address 192.168.0.1 255.255.255.0 encapsulation ppp async mode dedicated peer default ip address 192.168.0.10 ppp authentication chap ! interface FastEthernet0 no ip address shutdown speed auto ! interface Async5 no ip address ! ip classless no ip http server ! line con 0 transport input none line 1 password cisco login modem InOut transport input all stopbits 1 speed 115200 flowcontrol hardware line aux 0 login transport input all speed 115200 line vty 0 4 login !
