Configuring the HP AdvanceStack Internet Router
Configuring ISDN
Router (config-if)# isdn spid1 SPID_no [LDN]
Router (config-if)# isdn spid2 SPID_no [LDN]
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-thresholdor ppp multilink command to set up a second B channel.
For bandwidth on demand, enter the load-thresholdcommand 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-groupcommand to specify the number of the group permitted to access the router:
Router (config-if)# dialer-groupgroupnumber
11. Enter the exit command to exit interface configuration mode.
