Bridging 2 VLANs

RouterOS Forwarding Protocols
1

Hello

I have a VLAN on ether4 and another VLAN on SFP, I need to bridge these 2 to make a Layer-2 network for the customer, problem is as soon as I bridge these two all other VLANs on these interfaces go down i.e. traffic stops to flow and these 2 VLANs still don’t come on the same Layer-2

How can I achieve the said task of bridging these 2 VLANs

Any suggestions??

Thanks

Well put the two vlans under the same bridge, and ip/dhcp server on that bridge?

I tried that but all the other VLANs on the interface stop working, No DHCP on the bridge
No IP also as want to create a seamless Layer-2 for customer

Customer end point 1 <–(VLAN10)–> Mikrotik CCR ether 4

Mikrotik CCR SFP1 <–(VLAN20)–> Customer end point 2

need to bridge/switch VLAN10 and VLAN20

add the vlan to your in interface - and bridge them. This is correct for this.

From what I understand this is what we did in interface is SFP and out interface is ether4 VLAN on both and bridged them
THIS causes whole traffic on the interfaces to STOP i.e. all layer-2 connectivity is lost (to other VLANs on these interfaces )

Then it definitely looks like a bug. Make supout and send it to support.

Done doing it now
