Dear Friends,

I am using RB450G Board, i have created 4 VLANs on Ether2 interface and this ether2 interface connected to Switch Trunk Port and some switch ports are configure with different diffrenet vlans.

What i want is, i am assigning ip address on ether2 and it should work on all vlan port of switch.

i tried it but not working, it is working only on switch port which is in vlan1.

Please assist me to do so.

For example:

172.16.0.0/24 - Untagged
172.16.1.0/24 - vlan2
172.16.2.0/24 - vlan3
172.16.3.0/24 - vlan4

interface vlan add vlan-id=2 interface=ether2
interface vlan add vlan-id=3 interface=ether2
interface vlan add vlan-id=4 interface=ether2

Untagged
ip address add address=172.16.0.1 netmask=255.255.255.0 network=172.16.0.0 interface=ether2 disabled=no

taggged vlan
ip address add address=172.16.1.1 netmask=255.255.255.0 network=172.16.0.0 interface=vlan2 disabled=no
ip address add address=172.16.2.1 netmask=255.255.255.0 network=172.16.0.0 interface=vlan3 disabled=no
ip address add address=172.16.3.1 netmask=255.255.255.0 network=172.16.0.0 interface=vlan4 disabled=no

i want to add an IP on ether2 for ex: 10.164.164.2/24

what i want is if i assigned ip 10.164.164.3 on a pc which is connected to switch accessing vlan 124 it should work, is that possible?

Vlans separate L2 domains. You cant have a single L3 address across multiple L2 domains.

Bridge the vlans, and then assign the IP to the bridge.

Because you want to use vlan124 on a switch you have to assign 10.164.164.2/24 to vlan124 interface on a RB. Then it will work. That`s how i do.

I have assigned class b subnet ip on every vlan interface, its working fine, now i want is i want to assign class a subnet ip on ether2 or one of any vlan interface, but it should work on all vlan interface, if i bridge all vlan interface may be it will not work.

Yes, it will not work. If an interface is in bridge, routeros can’t route to this interface.
