7. Configure the router for PPP encapsulation and CHAP authentication:
Router (config-if)# encapsulation ppp
Router (config-if)# ppp authentication chap
8. Enter the
load-threshold
or
ppp multilink
command to set up a second
B channel.
For bandwidth on demand, enter the
load-threshold
command to set the
ISDN load threshold. The load threshold determines the percentage of
network load at which the second ISDN B channel is activated. The value
ranges from 1 to 255 (100 percent). In the following example, the value of
128 means that when the first B channel reaches 50 percent of its band-
width capacity (128 equals 50 percent of 255), the second B channel will
activate to assist with the bandwidth load:
Router (config-if)# dialer load-threshold 128
Alternatively, you can use Multilink PPP to activate a second ISDN line.
For Multilink PPP to work, the router must be running Cisco IOS
Release 11.0(3) or a later release (cannot be a non-IOS HP router), and
both the current router and target router must support Multilink PPP:
Router (config-if)# ppp multilink
9. Enter the
dialer map
command to provide the information necessary to
successfully route packets to the target router. Do not use periods or
hyphens when entering the number to dial:
Router (config-if)# dialer map protocol targetBRIport_ipaddress name
targetrouter_number
10. Enter the dialer-group command to specify the number of the group
permitted to access the router:
Router (config-if)# dialer-group groupnumber
11. Enter the exit command to exit interface configuration mode.
