Configuring SDLC

Problem

You want to configure a serial port to connect to an SDLC device so that it can use DLSw to talk to a central mainframe.

Solution

The global configuration commands in this example are identical to those shown in Recipe 15.1 for using DLSw+ to connect two Token Rings. The central router’s configuration is identical to what was used in Recipe 15.1, so the following only shows the remote branch configuration:

dlsw-branch#configure terminal
Enter configuration commands, one per line.  End with CNTL/Z.
dlsw-branch(config)#interface Loopback0
dlsw-branch(config-if)#ip address 10.1.2.5 255.255.255.252
dlsw-branch(config-if)#exit
