Switched PPP Multilink Configuration

XSR User’s Guide 10-35

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<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 following commands add a dialer pool and dialer group, and specify MLPPP call destination
Node A on Node B’s Dialer interface 1. Spoofing also is enabled by the

dialer map

command.

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>)#dialer-group 3
XSR(config-if<D1>)#dialer idle-timeout 20
XSR(config-if<D1>)#dialer map ip 10.10.10.1 2300
XSR(config-if<D1>)#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:

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
