MSR系列路由器
ISDN回呼功能的配置
关键词：MSR; ISDN; 回呼
一、组网需求：
两台MSR路由器通过E1线路直连，实现ISDN Pri回呼功能
设备清单： MSR系列路由器2台，MIM-2E1模块2个，E1线1根。
二、组网图：
三、配置步骤：
|
RTA配置 |
|
# sysname
rta # dialer-rule
1 ip permit # controller
E1 6/0 pri-set clock master # controller E1 6/1 # interface Serial6/0:15 link-protocol ppp ip
address dialer enable-circular dialer-group 1 dialer number 6688012 isdn protocol-mode network //指定回呼的号码为6688011 isdn calling 6688011 |
|
RTB配置 |
|
# sysname
rtb # dialer-rule
1 ip permit #
controller
E1 6/0 pri-set # controller
E1 6/1 # interface
Serial6/0:15 link-protocol
ppp ip
address dialer
enable-circular dialer-group
1 dialer
route i //配置允许号码6688011进行回呼 dialer call-in 6688011 callback |
四、配置关键点：
1) 指定回呼号码
2) 设置RTA的Serial6/0:15下ISDN协议模式为network，RTB默认为user
2) 假如中间有其它设备注意互连端口的工作模式，是主还是从，是网络侧还是用户侧。
五、结果验证
1) 从RTA ping RTB的接口地址，触发拨号：
<rta>ping

%Dec 26 16:57:26:188 2006 rta IFNET/4/UPDOWN:
