Dial-on-Demand Using ISDN Lines in a Frame Relay Network
Figure B-2 shows a frame relay network. In this network, BRI channels are used
as dial-on-demand connections.
This example assumes the following:
• Both routers are ASNs.
• The ISDN switch type is BRI NI1.
• The switches can support dial lines.
• There is no incoming call filtering.
• Sending complete IEs are not used for call setup.
• The adaption rate is 64 Kb/s.
• CHAP is the PPP authentication protocol.
• IP is the only LAN protocol configured.
• Only one phone number and SPID are used. (BRI lines usually have two
phone numbers and SPIDs.)
