Overview of Dial on Demand/Bandwidth on Demand

The XSR's Dial on Demand/Bandwidth on Demand applications provide high-speed, available-
when-needed dial services over point-to-point or multipoint PPP ISDN connections. Different
network topologies can be configured for different applications - mainly under Dialer Interface
configuration mode - including the following:
• Dial on Demand
–
–
–
–
–
• Switched PPP Multilink
–
• Backup
–
–
The caveats below apply to the XSR's support of switched multilink connections:
• They use the dialer, they are set up in Dialer interface mode and must include an ISDN
interface or associated modem.
• Configuring switched connections on a Serial line is unnecessary, the process is performed
automatically.
• Leased-line connections are supported and must be configured in Multilink interface mode.
• Support on FastEthernet/GigabitEthernet ports is not available.
