The MSTP enable state andforwarding state of each selected port in an aggregation group is consistent with those of thecorresponding Layer 2 aggregate port.z Though the member ports of an aggregation group do not participate in MSTP calculation, the portsstill reserve its MSTP configurations for participating MSTP calculation after leaving theaggregation group.Configuring MSTPConfiguring an MST RegionMake the following configurations on the root bridge and on the leaf nodes separately.Follow these steps to configure an MST region:To do...
