Concur Holvoe…
The post made is nonsensical, based on the experience on this forum I have seen all manner of setups and none of the threads examples seem out of place compared to that of which one is exposed to here. The intent of the article is to help users navigate through implementing vlans via vlan-filtering=yes, and the examples are 'fictionary and any resemblance to actual configs is not intentional, nor were any bunny rabbits harmed during the process. The post misses the mark by a continental mile.
