Configuring DoD/BoD
10-26 Configuring Dialer Services
XSR(config)#interface dialer 1
XSR(config-if)#no shutdown
XSR(config-if)#dialer pool 25
XSR(config-if)#encapsulation ppp
XSR(config-if)#dialer idle-timeout 35
XSR(config-if)#dialer-group 3
XSR(config-if)#dialer map ip 10.10.10.2 2400
XSR(config-if)#ip address 10.10.10.1 255.255.255.0
The following command defines interesting packets for the dial out trigger by configuring access
list 101 to pass all Type 8 source and destination ICMP traffic up to 35 idle seconds:
XSR(config)#access-list 101 permit icmp any any 8
The following command maps ACL 101 to dialer group 3:
XSR(config)#dialer-list 3 protocol ip list 101
Node B Configuration
The following commands add a dialer pool member and set the Central Office switch type on BRI
port 1/0:
XSR(config)#interface bri 1/0
XSR(config-if)#isdn switch-type basic-net3
XSR(config-if)#dialer pool-member 22
XSR(config-if)#no shutdown
The following commands add a dialer pool and dialer group, and specify MLPPP call destination
Node A on Node B’s Dialer interface 1. If the line is idle for 30 seconds, it is brought down.
XSR(config)#interface dialer 1
XSR(config-if)#no shutdown
XSR(config-if)#dialer pool 22
XSR(config-if)#encapsulation ppp
XSR(config-if)#dialer-group 7
XSR(config-if)#dialer idle-timeout 30
XSR(config-if)#dialer map ip 10.10.10.1 2300
XSR(config-if)#ip address 10.10.10.2 255.255.255.0
The following command defines interesting packets for the dial out trigger by configuring access
list 105 to pass all Type 8 source and destination ICMP traffic up to 30 idle seconds:
XSR(config)#access-list 105 permit icmp any any 8
The following command maps ACL 105 to dialer group 7:
XSR(config)#dialer-list 7 protocol ip list 105
PPP Point-to-Point Configurations
The following sample configuration is a PPP point-to-point topology, as illustrated in Figure 10-12
