Switched PPP Multilink Configuration

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

Switched PPP Multilink Configuration

Bandwidth-on-Demand

This example configures multilink PPP over ISDN together with BoD as shown in Figure 10-16.
