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 !
Router2: hostname router2 user router1 password cisco ! isdn switch-type basic-net3 ! interface bri 0 ip address 192.200.10.2 255.255.255.0 encapsulation ppp dialer map ip 192.200.10.1 name router1 571 dialer load-threshold 80 ppp multilink dialer-group 1 ppp authentication chap ! dialer-list 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:
