RB760IGS ignores VLAN settings

Sun Jan 10, 2021 4:32 pm

Hello, for some reason my router refuses to send packets to VLAN interfaces even though vlan filtering is on, PVIDs are set correctly, I can see Bridge/VLANs winbox menu reporting VLANs as being correctly tagged/untagged etc. But in interfaces menu I see traffic present only on a given ethernet interface and a bridge, but 0 bps on both VLANs

Configuration included below, it's pretty basic (just tag some ports with 1 and accept tagged with 1000). What exactly am I missing?

When you have vlan interface on bridge, then in "/interface bridge vlan" it must be tagged also on bridge interface, e.g.:
/interface bridge vlan
add bridge=bridge tagged=bridge,ether4,ether5 vlan-ids=1000
Excessive quoting is useless and annoying. If you use it, please consider if you could do without it.
