Configuring the Router for the First Time
Configuring the ISDN BRI Interface
This section describes how to configure the ISDN BRI interface. If your router does not
include an ISDN BRI interface, proceed to the next section, “Configuring Ethernet or Token
Ring Interfaces.”
The ISDN BRI interface is configured to allow connection to ISDN WANs. Determine
which protocols to support on the ISDN BRI interface and enter the appropriate responses.
In the following example, the system is configured for IP, AppleTalk, and IPX:
Configuring interface BRI0:
Is this interface in use? [yes]
Configure IP on this interface? [yes]
IP address for this interface: 172.16.71.1
Number of bits in subnet field [0]: 8
Class B network is 172.16.0.0, 8 subnet bits; mask is
255.255.255.0
