Click on the exhibit below.
In the diagram below, SAP 1 is put into the blocking state as a result of the spanning tree protocol. What will occur in the VPLS instance if SAP 2 goes down and SAP 1 transitions to the forwarding state? Select the most accurate statement.
- A. Stale information will be used within the VPLS instance to forward traffic until the FDB ages out.
