MSR系列路由器
单通道轮询DCC基本呼叫功能的配置
关键词:MSR; ISDN; 轮询DCC
一、组网需求:
两台MSR路由器通过E1线路实现轮询DCC呼叫功能
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 # //建立拨号访问组1,允许IP报文通过,并触发拨号 dialer-rule 1 ip permit #
controller
E1 6/0 pri-set //因为是E1背靠背直连,所以设本端E1接口为主时钟 clock master # controller E1 6/1 # interface Serial6/0:15 link-protocol ppp ip
address //在本接口使能轮询DCC dialer enable-circular //将本接口置入拨号组1中 dialer-group 1 //设定去往单个对端的拨号串 dialer number 6688012 //设置本端为网络侧 isdn protocol-mode network |
RTB配置 |
# sysname rtb # dialer-rule 1 ip permit # vlan 1 # controller E1 6/0 pri-set # interface Serial6/0:15 link-protocol ppp ip
address dialer enable-circular dialer-group 1 dialer
number 6688011 |
四、配置关键点:
1) 设置RTA为主模式,RTB不用设置,默认为从模式
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-Serial6/0:15]ping
Request time out
%Dec 22 11:23:28:388 2006 rta IFNET/4/UPDOWN:
Line protocol on the interface Serial6/0:2 is UP
%Dec 22 11:23:28:398 2006 rta IFNET/4/UPDOWN:
Protocol PPP IPCP on the interface Serial6/0:2 is UP
Request time out

2) 查看隧道接口的状态如下:
[rta-Serial6/0:15]dis isdn call-info
Serial6/0:15(Network-side) :
Link Layer 1: TEI = 0, State = MULTIPLE_FRAME_ESTABLISHED
Network Layer: 1 connection(s)
Connection 1 :
