10-34 Configuring Dialer Services
The following command defines interesting packets for the dial out trigger by configuring ACL 101
to pass all Type 8 source and destination ICMP packets:
XSR(config)#access-list 101 permit icmp any any 8
Dial-in Router Example
The following commands add a dialer pool and configure PPP Multilink on XSR-Andover’s Dialer
interface 1:
XSR(config)#interface dialer 1
XSR(config-if)#encapsulation ppp
XSR(config-if)#ip address 172.22.85.2
XSR(config-if)#ppp multilink
XSR(config-if)#dialer pool 1
XSR(config-if)#no shutdown
The following commands add a pool member and configure the primary-ni switch on T1 interface
2/3:
XSR(config)#controller t1 2/3
XSR(config-controller)#switch-type primary-ni
XSR(config-controller)#dialer pool-member 1
XSR(config-controller)#no shutdown
MLPPP Multipoint-to-Multipoint Configuration
The following configuration, as shown in Figure 10-11 , enables the setup of a switched MLPPP
group when access list-defined data traffic is sent to a remote site. Both peer nodes can initiate and
accept switched MLPPP calls.
Node A 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 25
XSR(config-if)#no shutdown
The following commands add a dialer pool and dialer group, and specify MLPPP call destination
Node B on Node A’s Dialer interface 1. If the line is idle for 20 seconds, it is brought down.
XSR(config)#interface dialer 1 multi-point
XSR(config-if)#no shutdown
XSR(config-if)#dialer pool 25
XSR(config-if)#encapsulation ppp
XSR(config-if)#dialer idle-timeout 20
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
XSR(config-if)#ppp multilink
The following command defines interesting packets for the dial out trigger by configuring ACL 101
to pass all Type 8 source and destination ICMP packets up to 20 idle seconds:
