I'm reading the SWITCH foundation learning guide, and it states that a trunk with mismatched native VLANs can lead to a loop because BPDUs are sent to the IEEE MAC address 0180.c200.0000
I think I understand at a very high level how this could happen: The root bridge of one of the VLANs would be superior to the root bridge of the other VLAN, and some of the switches would begin to converge around the root bridge from the wrong VLAN. However, this situation is still fuzzy around the edges to me, which usually means I'm missing something fundamental. Am I? Thanks!
