is this possible

RouterOS General

Is it possible to put 3 networks down a fiber connection then break them out at the other end? If so how would I do it in non programmers terms. sorry about the quality of the drawing have a broken finger :open_mouth:

Sure, thatā€™s what VLAN is for:

1 address range for cameras 1 for VOIP and the other for internet and hot spots. Thanks not touched VLANS before.

Yes, of course it is possible.
It is called VLANs.
And you even donā€™t need routers for it - managed switches will suffice.

5

@xvo its an interVLAN networkā€¦ you need a router to block the L3 communication between VLANs.

6

How do I block L3 communication between VLANs? This is a new area to me.

With a routerā€¦
Here is a nice article about VLANs http://forum.mikrotik.com/t/using-routeros-to-vlan-your-network/126489/92

EEEhhh, what? :open_mouth:

Please, tell me, what will change if you swap the two routers on the scheme above with two managed switches.

In OP nothing is said about interVLAN routing, only about squeezing 3 separate networks through one physical line and keeping them separate.

Nothing was said, unless you see the photo againā€¦
InterVLAN routing
Switch works at OSI layer 2 so it uses only Ethernet header to forward and does not check IP header. For this reason we must use the router that is working as a gateway for each VLAN.

OP said

To me this sounds a job for a pair of VLAN switches without any routing capability whatsoever.

11

Same for me.

Thanks Zacharias this is well out of my comfort zone looking like I will have to get some one in for this. Got to get 5 miles of fiber put in next I have some boxes ready for deployment so will get 2nd party to set the VPNā€™s up for me, network will be done in stages. Phase 1 completion planned for early April. This will be VOIP server and phones local Internet access and first hot-spot. Along with first batch of security cameras.

You are welcomeā€¦ yes that might me better.

I wonder how @xvo and @mkx would isolate those subnets on L2 and L3 with the use of only managed switchesā€¦
Am just happy that am a step aheadā€¦ :laughing:

14

By 1 hour time zone wise :laughing:

15

Each of the networks can have itā€™s own router, for example.

Ahead of what? Common sense? :laughing:
Yeah, you are right, thatā€™s your feature - jumping to conclusions based on your imagination only.
Seen that several times.
No offence, though. :wink:

xvo this is a new project out of what I have done before. So looking for some help and constructive comments!

As I wrote from the start - two devices on you picture donā€™t have to be routers.
You can do such link with two managed switches.
And it wonā€™t be hard to configure them.
But, that is all that can be said from your picture.

If you want a deeper advice, you can provide more info about your planned network: topology, needed bandwidth, number of devices, etc.
But from your next posts it is clear, that despite the task from your original post can be solved easily, the whole project is quite complex.
So after all, your idea to hire a professional to do it is a right one.
And for him there will be no problem to make your fiber link work the way you described it.

Thanks xvo its just a big learning curve for me as I have always dealt with simple networks this one is a big challenge for me and a lot for me to learn. I am an engineer not a software person wires, wifi and fiber I can understand the programming side of things I struggle with.

Bottom line: the answer to your original question is that you definitely can use one optical fiber for multiple isolated networks, that is common practice, and not rocket science at all. So you can safely start ā€œdigging trenchesā€ for your line and return to the decision whether you want to ā€œstruggleā€ configuring your network yourself or hire someone to help you somewhen later on your project :slight_smile:

yes xvo dig and learn. Thanks
