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
MLPPP Point-to-Point Configurations
The following MLPPP point-to-point topology can be used for Bandwidth on Demand
applications, as illustrated by Figure 10-14. This example creates three switched lines linking users
on XSR-Toronto’s network with those on XSR-Andover’s network.
