DHCP Server with Multiple VLAN's

RouterOS General
1

Hello,

Current setup:

RouterBoard 951G 2HnD OS ver 6.1

Ether1 - Gateway
Ether2 - Master- None - 192.168.10.254
Ether3-5 Master - None - No IP assignment not used

VLAN, 10, 30 and 50 created

VLAN 30 - 192.168.30.254
VLAN 50 - 192.168.50.254

VLAN’s 30 and 50 and ether2 are assigned to the default bridge-local port. VLAN 10 is the management untag port between the router and the layer 2 switch.

Ether2 is connected to a layer 2 switch that does tagging. VLAN’s 10, 30 and 50 are also on the layer 2 switch.

Created a DHCP server for VLAN 50 using the setup wizard and assigned it to the bridge-local group. Also created a DHCP relay on ether2 pointing to VLAN 50 layer 3 interface.

Clients on the layer 2 switch with their ports in vlan 50 untag cannot receive an IP address from the DHCP server.

Any help will be appreciated.

It probably has something to do with how you are bridging multiple networks together and not routing between them.

if all vlans are on the router inter-vlan routing should be already taking place

But you are putting them in a bridge! Bridge is not routing … why don’t you just assign the vlans to an interface and not a bridge? Then they will be routed together and on the same physical interface.
