3.2.4 Two-Switch coupling with control line
Figure 20: Example of Two-Switch coupling with control line
The coupling between two networks is effected by the main line (thick blue
line). If the main line fails, the redundant line (thick blue dotted line) takes
over coupling the two networks.
The coupling is effected by two Switches.
The Switches send their control packets via a control line.
The Switch to which you connect the main line, and the Switch to which you
connect the redundant line, are partners as regards the coupling.
