Configuring Dialer Services
The following commands define a dialer group, add a dialer pool, enable
MLPPP, set a 20-second idle timeout, and map BRI interface 1/0 to Dialer
interface 1. The
min-links command directs the XSR to maintain a
minimum of two links over the switched line. The
dialer map command
directs Node A to call Node B, specifying Node B’s IP address and phone
number, as well as enables spoofing.
XSR(config)#interface dialer 1
XSR(config-if<D1>)#no shutdown
XSR(config-if<D1>)#dialer pool 25
XSR(config-if<D1>)#encapsulation ppp
XSR(config-if<D1>)#dialer idle-timeout 20
XSR(config-if<D1>)#dialer-group 3
XSR(config-if<D1>)#dialer map ip 10.10.10.2 2400
XSR(config-if<D1>)#ip address 10.10.10.1 255.255.255.0
XSR(config-if<D1>)#ppp multilink
XSR(config-if<D1>)#multilink min-links 2
The following command defines interesting packets for the dial out trigger by
configuring ACL 101 to permit all Type 8 source and destination ICMP traffic:
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 (Called Node) Configuration
The following commands add a dialer pool member with the Central Office
switch type to BRI interface 1/0:
XSR(config)#interface bri 1/0
XSR(config-if<BRI-1/0>)#isdn switch-type basic-net3
XSR(config-if<BRI-1/0>)#dialer pool-member 22
XSR(config-if<BRI-1/0>)#no shutdown
The commands below add a dialer pool and enable MLPPP on Dialer port 1:
XSR(config)#interface dialer 1
XSR(config-if<D1>)#no shutdown
XSR(config-if<D1>)#dialer pool 22
XSR(config-if<D1>)#encapsulation ppp
XSR(config-if<D1>)#ip address 10.10.10.2 255.255.255.0
XSR(config-if<D1>)#ppp multilink
