Chapter 8 Switched PPP Multilink Configuration
Configuring Dialer Services
Switched PPP Multilink Configuration
Bandwidth-on-Demand
This example configures multilink PPP over ISDN together with BoD as
shown in Figure 32.
Figure 32 MLPPP Bandwidth on Demand Topology
Node A (Calling Node) 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 23
XSR(config-if<BRI-1/0>)#no shutdown
The following commands define a dialer group, add a dialer pool, enable
MLPPP, set a load threshold of 3 links, and map BRI interface 1/0 to Dialer
interface 1. The
load-threshold command enables BoD by making the
XSR maintain three links over the switched line. The
dialer map command
directs Node A to call Node C, specifying Node C’s IP address and phone
number as well as enables spoofing on the network.
XSR(config)#interface dialer 1
XSR(config-if<D1>)#no shutdown
XSR(config-if<D1>)#dialer pool 23
XSR(config-if<D1>)#encapsulation ppp
XSR(config-if<D1>)#ip address 10.10.10.1 255.255.255.0
XSR(config-if<D1>)#dialer map ip 10.10.10.3 2500
