16.12.1 16.9.1

Description (partial)

In case of MST, if a trunk port is configured to allow only some vlans but not all of an MST instance, we see that ingress flooding happens on all the vlans in that MST instance instead of blocking non-allowed vlans.

MST with trunk allowed vlans configured to allow some but not all vlans of the MST instance.
