Multiple networks in 1 VLAN

We are planning to have 3 different networks in one VLAN. Is that possible?

Say for example:

192.168.1.0/24

192.168.2.0/24

192.168.3.0/24

Could we have all these networks classified in one VLAN?

Not a good practice but you can configure this. Under the layer 3 VLAN interface use one subnet for primary addresse and secondary addresses for the others.

What if there are three networks altogether? What you have suggested can accomodate up to 2 networks.

I just realized that I can have more than secondary address. Thanks .
