Hello Folks,

I wanted to know if its possible and make sense,to have 2 VLANs with in the same subnet ? i.ee id like 2 VLANs say 20 and 21 and add 1 port to both the VLANs and another to just 21.
Please note that the hosts connected to these ports are in the same subnet (192.168.28.0/24) & the default gateways for both the VLANs is the same.

VLAN 20 - Tagged port 35,Untag 29
VLAN 21 - Tagged port 29,Untag 35

I cant seem to reach the host from one VLAN to another VLAN.Am i doing anything wrong ?

Thanks !!

VLANs are used to separate broadcast domains (subnets). You can tag multiple VLANs on a single port. You can only have one untagged VLAN per port as well.

Good question! but then there is another way one can see. if we have to use different subnet, they why use vlan at all? probably answer to this will clear my confusion 
