Example: Multilink PPP on One ISDN Interface

This example enables Multilink PPP on the BRI 0 interface. Because

an ISDN interface is a rotary group by default, when o ne BRI is con-

figured, no dialer rotary group config uration is required.

Configure Multilink PPP on Multiple ISDN BRI Interfaces

To enable Multilink PPP on multiple ISDN BRI interfaces, set up a di-

aler rotary interface and configure it for Multilink PPP and then con

figure the BRIs separately and add them each to the same rotary group.

Beginning in global configuration mode, set up the dialer rotary inter-

face for the BRI interfaces:

1. Specify the dialer rotary interface.

interface dialer

number

2. Specify the protocol address for the dial er rotary interface.

ip address

address mask

3. Enable PPP encapsulation.

encapsulation ppp

4. Specify in-band dialing.

dialer in-band

5. Specify the dialer idle timeout period, using the same timeout pe-

riod as the individual BRI interfaces.

dialer idle-timeout
