11.5 bri口拨号的配置
11.5.1基本配置
【配置】
参见异步口拨号的配置，只是不需要配置如下命令
[Router-bri0]modem
[Router-bri0]baudrate 57600
[Router-bri0]asy mode protocol
11.5.2使用BRI两个B通道进行MP绑定配置
【配置】
!
dialer-rule 1 ip permit /配置拨号访问控制列表/
!
interface Bri0
link-protocol ppp
ppp mp /使能ppp mp/
ppp mp min-bind 2 /mp同时发起呼叫的最少通道数为2，使用2个B通道进行呼叫/
ip address 10.1.1.2 255.255.255.252
isdn service data
isdn service speech
dialer enable-circular /启动轮询DCC/
dialer-group 1 /引用拨号访问控制列表/
dialer threshold 1 in-out /设置流量门限为0%，直接启动2B进行捆绑/
dialer number 12345678 /ISDN的拨号号码/
!
ip route-static 0.0.0.0 0.0.0.0 bri 0 preference 60
!
return

【注意】
1、BRI 2B捆绑和BRI普通拨号在配置上，增加了“ppp mp”、“ppp mp min-bind 2”、“dialer threshold 0 in-out”命令，其它配合和拨号配置一致。
