VSX and MSTP loop-protect configurations (physical and logical views)

The figures in this topic show the physical and logical views for VSX and MSTP loop-protect configurations with MST0 as the default instance.

The configuration from the previous figure is shown in its logical view, so that you can see how the network views the configuration. For example, the following figure shows that the VSX distributed pair as one switch. The ports on Agg-2 are blocking traffic. The logical view in the next figure shows that the traffic is distributed so that the traffic continues to flow.
