Trouble creating a VLAN bridge

RouterOS General
1

Hi,

I am trying to create a vlan bridge with trunk ports on my CCR-1009 but it seems it is not working. I want to have Combo1 and ether2 as trunk ports on my CCR.

I have read a lot og posts and documentation but somehow something is not working - my laptops on the switch connected to the trunkports do not get an IP from the DHCP server.
Just to be sure I tested with another switch where I know the trunkport and VLAN 30 works and the same result, so right now I am ruling out the receiving end of the trunk, so the problem must be at the sending end.
When I torch the interface I can see VLAN tags of COMBO1 which is why I don’t understand why it is not working.


To start with I tested only with VLAN30 - when I get this working others will come.
My configuration is a per below - any hints ?

/interface bridge
add frame-types=admit-only-vlan-tagged ingress-filtering=yes name=Trunk-bridge \
    vlan-filtering=yes
/interface bridge port
add bridge=Trunk-bridge frame-types=admit-only-vlan-tagged ingress-filtering=\
    yes interface=ether2
add bridge=Trunk-bridge frame-types=admit-only-vlan-tagged ingress-filtering=\
    yes interface=combo1
/interface bridge vlan
add bridge=Trunk-bridge tagged=ether2,combo1 vlan-ids=30


/interface vlan

add interface=Trunk-bridge name=vlan30_trunk vlan-id=30

/ip dhcp-server
add address-pool=ipcam disabled=no interface=vlan30_trunk name=IPCAM

/ip dhcp-server network
add address=10.30.30.0/24 comment=IPCAM dns-server=1.1.1.1 gateway=10.30.30.1

You have to add Trunk-bridge interface as tagged member of a VLAN in /interface bridge vlan if you want router’s CPU to interact with said VLAN through vlan interface vlan30_trunk.

Thanks - that worked :slight_smile:
