802.1Q Vlan Tagging between RB433 and CRS

RouterOS General
1

Hi!

I am trying to setup a VLAN-Trunk between a RB433 and a CRS. Just one Vlan tagged (101) and one Vlan untagged (1)

My first try was not to use the switch-chip of the CRS. On both sides, I added a VLAN-interface to ether1 (ether1-vlan101) and assigned an IP to it. The two systems cannot ping each other through ether1-vlan101 - just through ether1 (untagged). Destination was unreachable.

/interface vlan
add interface=ether1 l2mtu=1518 name=ether1-Vlan101 vlan-id=101
/ip address
add address=192.168.1.168/24 interface=ether1-Vlan101 network=192.168.1.0


My second try was to use the switch-chip on the CRS, but the RB433 does not offer that possibility. Of course, the systems did not see each other through vlan 101, too.

Can you give me a hint on how to set this up?

Thank you and best wishes,
Stril

If CRS has ports configured in a group by master-port, then create VLAN101 interface on the master-port and assign IP address to the VLAN101 interface, otherwise create VLAN101 interface on the ethernet interface towards the RB433.

Hello!

I could it get to work now:

Config on CRS:
/interface vlan
add interface=ether1 l2mtu=1518 name=ether1-Vlan101 vlan-id=101
/ip address
add address=192.168.1.168/24 interface=ether1-Vlan101 network=192.168.1.0

Config on RB433
/interface vlan
add interface=ether1 l2mtu=1518 name=ether1-Vlan101 vlan-id=101
/ip address
add address=192.168.1.169/24 interface=ether1-Vlan101 network=192.168.1.0

I just had a mistake with the port assignment.
