Chapter 3 Configuring with the Command-Line Interface Configuring ISDN BRI WAN Interface Cards Command Purpose Step 1 Router> enable Enter enable mode. Enter the password. Password: password Router# You have entered enable mode when the prompt changes to Router#. Step 2 Router# configure terminal Enter global configuration mode. You have Enter configuration commands, one per line. entered global configuration mode when the End with CNTL/Z. prompt changes to Router(config)#. Router(config)# Step 3 Router(config)# isdn switch-type basic-5ess Enter an ISDN switch type. See Table 3-5 for a list of ISDN switch types. Step 4 Router(config)# ip routing Router(config)# appletalk routing Router(config)# ipx routing Step 5 Router(config)# interface bri 0/0 Router(config-if)# Step 6 Router(config-if)# ip address 172.16.74.2 255.255.255.0 Router(config-if)# isdn switch-type basic-5ess Step 7 Router(config-if)# appletalk static cable-range 5-5 Router(config-if)# appletalk zone ZZBRI Router(config-if)# ipx network B004 Router(config-if)# isdn incoming-voice modem Step 8 Router(config-if)# exit Note Switch types configured in interface configuration mode override this setting for the configured interface. Enable routing protocols as required for your global configuration. This example uses IP routing, AppleTalk routing, and Internetwork Packet Exchange (IPX) routing. Enter the interface configuration mode. You have entered interface configuration mode when the prompt changes to Router(config-if)#. Assign the IP address and subnet mask to the interface. If you are configuring this interface for voice, enter the switch type instead of an IP address. Configure routing protocols on the interface. You must have previously enabled these protocols as part of global configuration. In this example, AppleTalk and IPX are being configured on the interface. If you are configuring this router for voice, use the isdn incoming-voice modem command. Exit back to global configuration mode. Step 9 Router(config-if)# memory-size iomem 40 Step 10 Router(config)# Ctrl-z Repeat Step 5 through Step 7 if your router has more than one BRI interface that you need to configure. By default, the router allocates 25 percent of DRAM to shared memory (used for data transmitted or received by network modules and WAN interface cards). If your router includes 16 or more ISDN BRI interfaces, you must increase the amount of shared memory by entering the memory-size iomem command. This example increases shared memory from 25 percent to 40 percent. When you finish configuring interfaces, return to enable mode.
