ISDN实现 DDR（ dialondemand routing）实例 : 设置如下： 14 Router1: hostname router1 user router2 password cisco ! isdn switchtype basic3 ! interface bri 0 ip address encapsulation ppp dialer map ip name router2 572 dialer loadthreshold 80 ppp multilink dialergroup 1 ppp authentication chap。 dialerlist 1 protocol ip permit ! Router2: hostname router2 user router1 password cisco ! isdn switchtype basic3 ! interface bri 0 ip address encapsulation ppp dialer map ip name router1 571 dialer loadthreshold 80 ppp multilink dialergroup 1 ppp authentication chap。 dialerlist 1 protocol ip permit ! Cisco 路由器同时支持回拨功能，我们将路由器 Router1作为 Callback Server,Router2作为 Callback Client。 与回拨相关命令 : 任务 命令 映射协议地址和电话号码，并在接口上使用在全局模式下定义的 PPP回拨的映射类别。 dialer map protocol address name hostname class classname dialstring 设置接口支持 PPP回拨 ppp callback accept 在全局模式下为 PPP回拨设置映射类别 mapclass dialer classname 通过查找注册在 dialer map 里的主机名来决定回拨 . dialer callbackserver [username] 设置接口要求 PPP回拨 ppp callback request 设置如下： Router1: hostname router1 user router2 password cisco ! isdn switchtype basic3 ! interface bri 0 ip address encapsulation ppp 15 dialer map ip name router2 class s3 572 dialer loadthreshold 80 ppp callback accept ppp multilink dialergroup 1 ppp authentication chap。 mapclass dialer s3 dialer callbackserver username dialerlist 1 protocol ip permit ! Router2: hostname router2 user router1 password cisco ! isdn switchtype basic3 ! interface bri 0 ip address encapsulation ppp dialer map ip name router1 571 dialer loadthreshold 80 ppp callback request ppp multilink dialergroup 1 ppp authentication chap。 dialerlist 1 protocol ip permit ! 相关调试命令 ： debug dialer debug isdn event debug isdn q921 debug isdn q931 debug ppp authentication debug ppp error debug ppp negotiation debug ppp packet show dialer show isdn status 举例 :执行 debug dialer 命令观察 router2 呼叫 router1,router1 回拨 router2的过程 . router1debug dialer router2ping router1 00:03:50: %LINK3UPDOWN: Interface BRI0:1, changed state to up 00:03:50: BRI0:1:PPP callback Callback server starting to router2 572 00:03:50: BRI0:1: disconnecting call 00:03:50: %LINK3UPDOWN: Interface BRI0:1, changed state to down 00:03:50: BRI0:1: disconnecting call 00:03:50: BRI0:1: disconnecting call 16 00:03:51: %LINK3UPDOWN: Interface BRI0:2, changed state to up 00:03:52: callback to router2 already started 00:03:52: BRI0:2: disconnecting call 00:03:52: %LINK3UPDOWN: Interface BRI0:2, changed state to down 00:03:52: BRI0:2: disconnecting call 00:03:52: BRI0:2: disconnecting call 00:04:05: : Callback timer expired 00:04:05: BRI0:beginning callback to router2 572 00:04:05: BRI0: Attempting to dial 572 00:04:05: Freeing callback to router2 572 00:04:05: %LINK3UPDOWN: Interface BRI0:1, changed state to up 00:04:05: BRI0:1: No callback negotiated 00:04:05: %LINK3UPDOWN: Interface VirtualAccess1, changed state to up 00:04:05: dialer Protocol up for Vi1 00:04:06: %LINEPROTO5UPDOWN: Line protocol on Interface BRI0:1, changed state to up 00:04:06: %LINEPROTO5UPDOWN: Line protocol on Interface VirtualAccess1, chang ed state to up 00:04:11: %ISDN6CONNECT: Interface BRI0:1 is now connected to 572 router1 4. ISDN访问首都在线 263网实例 : 本地局部网 地址为 ,属于保留地址，通过 NAT 地址翻译功能，局域网用户可以通过 ISDN上 263网访问 Inter。 263的 ISDN电话号码为 2633，用户为 263，口令为 263，所涉及的命令如下表： 任务 命令 指定接口通过 PPP/IPCP 地址协商获得 IP地址 ip address negotiated 指定内部和外部端口 ip nat {inside | outside} 使用 ppp/pap作认证 ppp authentication pap callin 指定接口属于 拨号组 1 dialergroup 1 定义拨号组 1允许所有 IP协议 dialerlist 1 protocol ip permit 设定拨号，号码为 2633 dialer string 2633 设定登录 263的用户名和口令 ppp pap sentusername 263 password 263 17 设定默认路由 ip route bri 0 设定符合访问列表 2 的所有源地址被翻译为 bri 0所拥有的地址 ip nat inside source list 2 interface bri 0 overload 设定访问列表 2，允许所有协议 accesslist 2 permit any 具体配置如下： hostname Cisco2503 ! isdn switchtype basic3 ! ip subzero no ip domainlookup ip routing ! interface Ether 0 ip address ip nat inside no shutdown ! interface Serial 0 shutdown no description no ip address ! interface Serial 1 shutdown no description no ip address ! interface bri 0 ip address negotiated ip nat outside encapsulation ppp ppp authentication pap callin ppp mult。
