In addition to the assumptions described in the “Before You Begin” section at the
beginning of this chapter, this configuration is based on the additional assumption
that both ISDN B channels are connecting to the same central-site router.
These are the major tasks in configuring your router for a leased-line ISDN
connection:
• Configuring Global Parameters
• Configuring Security
• Configuring IPX Routing
• Configuring the ISDN Line for Leased Line
• Configuring the Fast Ethernet Interface
• Clearing the ISDN Interface
• Configuring the ISDN Subinterfaces
• Configuring Dynamic IP Routing
• Configuring Command-Line Access to the Router
Figure 5-3 shows the configuration example that is used in this section.
