Re: Replaceing three switchs with one

So if I have Vlan1 on teh switch I don't need to create Vlan1 on my mikrotik router for example?

Thanks

You don't have to if you don't mind taking up extra switch ports.

Vlan 1 is generally the default untagged vlan on most managed switches. You don't necessarily need to tag traffic as Vlan 1 coming from the router as untagged traffic on that port will default to vlan 1 on the switch (usually).

What you are looking at doing is exactly what I've done here: »This morning's fun You wont have any issue with MTU or OSPF in this setup.

Here is the relevant config from the above setup:
MT:

And from the Cisco Switch:

On the MT the interface named 'Core_Switch' is the physical interface that is connected to port #1 on the switch. Personally I don't assign any ip address to that port as I use tagged traffic for management. Anything you assign to the physical interface as far as ip addresses etc. will equate to untagged traffic and will use the native/default vlan on the switch (usually vlan 1). Each Vlan interface can be manipulated just like it was a physical interface on the router.

On the switch port #1 is setup as a trunk port so that multiple tagged vlan traffic can pass and exiting traffic is tagged with the appropriate vlan. Subsequent ports are set as access ports (un-tagged).

So Using HSW (Horizontal South West access point) as an example from my configs. If you look at the MT config you'll see I have HSW assigned to vlan 29. Then looking at the cisco config you'll see that port 15 is set to access vlan #29 and my HSW access point is plugged into that port. My HSW access point does not tag it's traffic.
