Configuring SDLC for Multidrop Connections
Problem
You want to configure a serial port for an SDLC multidrop line supporting several devices.
Solution
SDLC supports multidrop connections. These are serial links that connect to several downstream devices in series. Each device has its own SDLC address, which must be configured in the router. The global DLSw configuration for this example is omitted here because it is identical to the previous example:
