| I was reading in the BCMSN book that there are instances that you will need to configure multiple subnets on the same VLAN. Is this something that is faily common?
Thanks | |

| you shouldn't really have to do that too often unless you use up all of your host addresses available on the subnet you are using. If that happened and you wanted more users in that subnet, then yes, you would have to put in another subnet. You could also use this for migrating ip's. for instance you were migrating from one subnet to another within the same vlan, you could have both up and migrate at your own pace, without much downtime. In my case though, if I had that many users in a vlan, I would probably just put the next subnet in another vlan. Guess it would depend on your requirements. | |

| Yep, it happens, though Cisco recommends against it. We have a couple of instances of it here and I suspect it's primarily because of existing groups joining exisiting groups for some sort of project, but I have never asked why...
