Inter-VLAN routing

Hi all,


For the moment, I have a very basic question: Does one always need a router while trying to route between multiple VLANs?


Obviously, my understanding is also that a VLAN is also equivalent to a subnet in the roughest of terms, i.e. non-subnetted hosts in 192.168.1.0/24, all 254 hosts must be in the same VLAN and it cannot be that 192.168.1.x (all odd numbers) be in VLAN 2 and 192.168.1.y (all even numbers) in VLAN 3.


Right?


Thanks a lot.


Kind regards.


PS: yes, I am learning, but some questions are not answer clear enough for me. Thanks.

Hi Ben,

For switching between Vlans. You properly use L3 switch to accomplish that. You can use a router to do intervlan-routing as well.

it cannot be that 192.168.1.x (all odd numbers) be in VLAN 2 and 192.168.1.y (all even numbers) in VLAN 3.

It's not possible. You may think of this way. 192.168.1.0/25 - Vlan2 and 192.168.1.128/25 - vlan3



HTH,
