云知道


在一個端口激活DIAL-ON-DEMAND ROUTING
命令：dialer in-band
指定一個端口為撥號訪問組：dialer-group group-number
指定一個單一電話號碼：dialer string dialer-string
斷線前空前等待時間：dialer idle-time seconds
定義一個或多個目的電話號碼表：
dialer map protocol net-hop-address dialer-string
限定傳輸?shù)腶ccess-list表或特定協(xié)議：
dialer-list dialer-group list access-list-number或
dialer-list dialer-group protocol protocol name(permit/deny/list access-list-number)
具體配置：
！
interface serial 0
ip address 131.108.126.1 255.255.255.0
dialer in-band
dialer-group 1
!
dialer map ip 131.108.126.2 55551234
!
dialer idle-timeout 300
dialer backup example
A) 同步V.25bits方式
configuration for routerA:
interface serial 10:0
backup delay 0 10
backup interface serial 110
ip address 16.217.30.2 255.255.255.252
!
interface serial 110
ip address 16.30.16.81 255.255.255.25.0
encapsulation ppp
dialer in-band
dialer string 8292
dialer-group 1
pulse-time 1
!
dilar-list 1 protocol ip permit
B) 輔助口作撥號備份

subinterface example (frame realay)
configuration for routerA:
interface serial 0
encapsulation frame-relay
interface serial 0.1 multipoint
ip address 11.10.11.1 255.255.255.0
frame-relay interface-dlci 41
frame-relay interface-dlci42
configuration for routerC:
interface serial 0
encapsulation frame-relay
interface serial 0.1 point-point
ip address 11.10.16.2 255.255.255.0
frame-realy interface-dlci 46
configuration for routerB:

interface serial 0.1 multipoint
ip address 11.10.11.3 255.255.255.0
frame-relay interface-dlci 43
frame-relay interface-dlci 44
!
interface serial 0.2 point-point
ip address 11.10.13.1 255.255.255.0
frame-realy interface-dlci 48
frame relay switching example
configuration for routerA:
frame-relay switching
no ip address
frame-relay encapsulation
frame-relay route 163 tun0 43
frame-relay intf-type dce
!
interface serial0
ip address 131.108.100.1 255.255.255.0
!
interface tu 0
tunnel source serial 1
tunnel destintion 131.108.13.2
configuration for routerB:
frame-relay switching
!
interface serial 0
no Ip address
frame-relay encapsulation
frame-relay router 9 tun0 43
frame-relay interface-type dce
!
int tu 0

channelized E1interface example
假設是7500系列路由器，E1接口（MIP板）在插槽4上面 。
一個CHANNEL-GROUP 可對應多個時間槽，本例中SERIAL4/0：1有5*64的速率
configuration for router :
controller e1 0
