Configuring Line Services
Conventional addressing designates routers A, B, and C as DCE (address = 01)
and routers X, Y, and Z as DTE (address = 03). If router A transmits a frame
across the virtual point-to-point circuit to X, X (the intended recipient), Y, and Z
all monitor the satellite broadcast. Because X, Y, and Z all perceive a properly
addressed frame, all three accept delivery and attempt to process the frame
contents, with unpredictable results.
To avoid such confusion, assign unique addresses to each end of a point-to-point
circuit using the Local Address and Remote Address parameters. Be sure to
reverse the local and remote addresses when you configure the other end of the
point-to-point circuit.
