MIKROTIK BRIDGE VLAN CONFIG

• create the bridge
• create an /interface/vlan on top of the bridge
• assign an IP address to the /interface/vlan
• set the pvid on the bridge ports
• define an /interface/bridge/vlan and set tagged/untagged ports. The bridge is a port as well, if you want the switch to have layer3 presence on the VLAN

Let's deconfigure the Helena VLAN 181 from hoshino/sabrina/helian

We'll work on hoshino first because it's not on the current useful path.

• /interface/bridge/vlan/remove 1
• no pvid to change because all ports in the VLAN are trunked, so they keep pvid 1
• remove IP address from /interface/vlan/HELENA: /ip/address/remove numbers=2
• remove the /interface/vlan: /interface/vlan/remove HELENA

Sabrina next:

• /interface/bridge/vlan/remove 1
• set pvid on ether7 back to VLAN 1
• no IP to remove because sabrina isn't present on VLAN 181
• no /interface/vlan to remove because sabrina isn't present on VLAN 181

helian last, helian is the gateway for the Persica/Helana VLAN 181

• /interface/bridge/vlan/remove 1
• no pvid to remove on bridge ports because this VLAN is only tagged
• remove the IP address from /interface/vlan/PersicaTunnel181
• delete the /interface/vlan/PersicaTunnel181

Cleanup helena now, because I fixed her DHCP and now she's back on VLAN 1 natively

• Delete the 10.10.181.2 IP address
• Remove custom routing rules
