hello Guys,

I am new to the mikrotik routerOS, i have a layer 3 mikrotik switch, CRS125-24G. I want to use this mikrotik to configure vlans with vlan interfaces (routing mode) and assign dhcp server to each vlan, and then to untag and tag switch ports with desired vlans. After i did my research, i see that when vlan is created , it should be assigned to an interface, and this interface will be a trunk port. but this is not my case, as i want to create a vlan, assign an ip for it, and untag it on several switch ports for example ( same mikrotik ).

Hope someone helps with this and give me some headlines on how the configuration shall be done,
thanks

Here's VLAN config manual for CRS1xx. Beware that routing capacity of CRS1xx devices is nowhere near wirespeed. If you need any decent throughput between VLANs you better buy proper router for that.
