Hello All!

I have a RB951Ui-2HnD router, on it I have setup vlans 10, 20, 30 and 99. Each vlan has its own DHCP server and running on specific ports. vlan99 on ether1, vlan10 on ether2 and ether3, vlan20 on ether4 and vlan30 on ether5. Everything seems working fine but a few issues:

dhcp_vlan10 and dhcp_vlan30 are not working
dhcp_vlan20 is giving default gateways as 0.0.0.0
dhcp_vlan99 is working perfectly fine

If someone can help I would greatly appreciate it <3

Are you trying to configure it like a switch/AP ?

/ip address
add address=192.168.99.1/24 interface=management_vlan network=192.168.99.0
add address=192.168.10.1/24 interface=bridge1 network=192.168.10.0
add address=192.168.10.254/24 interface=ether2 network=192.168.10.0
add address=192.168.10.253/24 interface=ether3 network=192.168.10.0
add address=192.168.20.254/24 interface=ether4 network=192.168.20.0
add address=192.168.30.254/24 interface=ether5 network=192.168.30.0
add address=192.168.20.1/24 interface=vlan20 network=192.168.20.0
add address=192.168.30.1/24 interface=vlan30 network=192.168.30.0

Red should be changed to:

/ip address
add address=192.168.99.1/24 interface=management_vlan network=192.168.99.0
add address=192.168.10.1/24 interface=vlan10 network=192.168.10.0
add address=192.168.20.1/24 interface=vlan20 network=192.168.20.0
add address=192.168.30.1/24 interface=vlan30 network=192.168.30.0

Here I think you are missing what ports are untagged:

/interface bridge vlan
add bridge=bridge1 tagged=bridge1 vlan-ids=10
add bridge=bridge1 tagged=bridge1 vlan-ids=20
add bridge=bridge1 tagged=bridge1 vlan-ids=99
add bridge=bridge1 tagged=bridge1 vlan-ids=30

Should be:

/interface bridge vlan
add bridge=bridge1 tagged=bridge1 untagged=ether2,ether3 vlan-ids=10
add bridge=bridge1 tagged=bridge1 untagged=ether4 vlan-ids=20
add bridge=bridge1 tagged=bridge1 vlan-ids=99
add bridge=bridge1 tagged=bridge1 untagged=ether1 vlan-ids=30

Sorry if any mistake is made here..

Thank you for you response.

i made all the changes and the results are:
dhcp_vlan99 works 100%
dhcp_vlan20 works 100%
dhcp_vlan10 gives out 0.0.0.0 as gateway
dhcp_vlan30 is not even found when I run ipconfig /renew

I am sorry for being such a pain in the a$$ with these questions and I am trying to configure it as a switch/router. wlan interfaces are shutdown I'm not using them (if that's your question)

Be careful, switch is not the same thing as router, so this configuration is not valid. What is your upstream router ?

Yeah my bad. Right now I am using it as a switch even though it is a router also. My entire network is basically just my laptop, the switch and a desktop computer that I try to ping. I am not routing to and from any other interface. I hope that answers your question

So what are you trying to achieve with this setup ? From where are you gettng internet connection ?

The problem here is no clue as to what you are trying to achieve.
Draw a network diagram that always helps. Should have a plan.

Detail where your ISP is in the mix, modem or router modem, where is your public IP,
what is the intended function of the mikrotik device etc......

I'm sorry I should have clarified. This is a practice lab, not a real setup. This is just a way to learn how to setup multiple vlans and inter-vlan routing, with each vlan being on its own subnet and having its own dhcp server. The diagram is pretty simple. 2 PCs connected to the router, each on a different VLAN.

Then reboot router to default configuration and start over, just add your configuration to default one. My advice.

Also, this is a must read if you are new: viewtopic.php?t=182373

Yeah this is the best thing to do.

Thank you anyway for bearing with me.

No problem, also you should check out youtuber TheNetworkBerg, he made a series of videos reagrding VLANs, routing, etc.
