设置ISDN交换类型 isdn switch-type switch-type1 接口设置 interface bri 0 设置PPP封装 encapsulation ppp 设置协议地址与电话号码的映射 dialer map protocol next-hop-address [name hostname] [broadcast] [dial-string] 启动PPP多连接 ppp multilink 设置启动另一个B通道的阈值 dialer load-threshold load 显示ISDN有关信息 show isdn {active history memory services status [dsl interface-type number] timers} 注：1.交换机类型如下表,国内交换机一般为basic-net3。 按区域分关键字 交换机类型 Australia basic-ts013 Australian TS013 switches Europe basic-1tr6 German 1TR6 ISDN switches basic-nwnet3 Norway NET3 switches (phase 1) basic-net3 NET3 ISDN switches (UK, Denmark, and other nations); covers the Euro-ISDN E-DSS1 signalling system primary-net5 NET5 switches (UK and Europe) vn2 French VN2 ISDN switches vn3 French VN3 ISDN switches Japan ntt Japanese NTT ISDN switches primary-ntt Japanese ISDN PRI switches North America basic-5ess AT&T basic rate switches basic-dms100 NT DMS-100 basic rate switches basic-ni1 National ISDN-1 switches primary-4ess AT&T 4ESS switch type for the U.S. (ISDN PRI only) primary-5ess AT&T 5ESS switch type for the U.S. (ISDN PRI only) primary-dms100 NT DMS-100 switch type for the U.S. (ISDN PRI only) New Zealand basic-nznet3 New Zealand Net3 switches 3. ISDN实现DDR（dial-on-demand routing）实例: 设置如下： Router1: hostname router1 user router2 password cisco ! isdn switch-type basic-net3 ! interface bri 0 ip address 192.200.10.1 255.255.255.0 encapsulation ppp dialer map ip 192.200.10.2 name router2 572 dialer load-threshold 80 ppp multilink dialer-group 1 ppp authentication chap ！ dialer-list 1 protocol ip permit !
