아래에도 VLAN 구성관련 문의를 드렸었는데요,

박건님께서 상세한 가이드를 해주셔서 이해에 많은 도움이 되었습니다. 다시한번 감사의 말씀을 드립니다.


이전 문의와 이어진 내용입니다만, 

다음과 그림과 같이 포트단위 VLAN을 구성하려고 합니다.

건물과 기능이 분산되어 있는 환경에서, VLAN을 구성하여 기능별 동일네트웍으로 이용하려는 목적입니다.


미크로틱 매뉴얼, 2CPU 사이트자료, 유튜브자료 그리고 가이드해주신 내용을 바탕으로 라우터와 스위치의 Configuration을 짜보았습니다

빠진부분은 없는지?, 수정할 부분은 없는지 봐주시면 감사하겠습니다.
