DHCP Over Multiple VLANS

RouterOS General
1

Hi There

Need some assistance on the below please

I have a Bridge with about 20 VLANS (FTTH from FNOs) in it. I have a DHCP server running on the Bridge assigning public IPs to clients

How can i get the the router to stop broadcasting across all VLANS? I have a CCR2004

Also, what is the best practice in setting up FTTH VLANS from differrent FNO using DHCP (not PPPOE)

Thanks

VLANs - different address on different ports
Can't get a simple bridge vlan to work

First read this article…

Second, stop using the bridge to do the serving, and assign
address, pool, dhcp server and dhcp-server network PER VLAN.
The vlans interface is the bridge.
DONE
now you are in charge and not the bridge!!

Thanks for the reply,

I actually had it split up first but I got stuck because I had to create individual public IP addresses per VLAN as well as its own IP pool with each gateway being the public IP. This was ineffective because I was using too many public IPs and had to create too many different pools. Am I doing something wrong here?

I now have 3 interfaces.
Interface 1 - this has 20 VLANS in
Interface 2 - this has 3 VLANS
Interface 3 - This has 2 VLANS

How can I make it so that all the above VLANS use the same IP Pool and Gateway without using a bridge?

The purpose of vlans is to separate traffic between subnets.
If you dont need separate subnets dont create so many vlans. Lump groups together for example.
Yes, you need to have all the pools addresses etc. but tis a one time setup.

These VLANS are from the Fibre Network Operators. Its how their lines connect to us so i cant change that unfortunately

If youre trying to stop broadcast traffic between client bridged vlans, I think you could to add the clients ports to the same horizon, and leave your internet port out of it.

Split horizon bridging.
