Software Release 2.7.1
C613-02047-00 REV A
On the Remote Office router, create PPP interface 0 to use the ISDN call
ROHO by entering the command:
create ppp=0 over=isdn-roho
Check the configuration with the commands:
show isdn call
show ppp
The call ROHO should appear in the output of the SHOW ISDN CALL
command. The output of the SHOW PPP command should show interface
ppp0 over ISDN-ROHO.
ISDN is now ready for use by routing protocols such as IP and IPX.
Configuring ISDN Dial on Demand
A PPP interface that uses an ISDN call as its physical interface can be
configured for dial-on-demand operation. The ISDN call is activated only
when data is transmitted, and is disconnected when the link is idle for a period
of time.
To configure ISDN dial-on-demand follow these steps
The following steps are required:
1. Configure BRI or PRI ISDN.
2. Create PPP interfaces.
1. Configure BRI or PRI ISDN.
Complete steps 1 to 5 of “Configuring Basic Rate ISDN” on page 76 , or
steps 1 to 4 of “Configuring Primary Rate ISDN” on page 79 .
2. Create PPP interfaces.
Create PPP interfaces to use the ISDN calls and enable the IDLE timer.
Using the example in step 6 of
“Configuring Basic Rate ISDN” on page 76 ,
on the Head Office router create PPP interface 0 to use the ISDN call
ROHO, enter the command:
create ppp=0 over=isdn-roho idle=on
On the Remote Office router, to create PPP interface 0 to use the ISDN call
ROHO, enter the command:
create ppp=0 over=isdn-roho idle=on
Setting the IDLE parameter to ON enables the idle timer and sets the
timeout period to 60 seconds. ISDN calls are disconnected no data is
transmitted over the link for 60 seconds. To enable the idle timer with a
different timeout period, specify a time in seconds instead of the value ON.
PPP interface 0 is now configured for dial-on-demand operation and any
routing protocols such as IP and IPX that are configured to use PPP interface 0
will automatically inherit the dial-on-demand functionality.
