I want to use a 元 switch in the distribution layer (as we are talking about) and a router in the core layer. :-)So applying what you guys have told me and what I have studyied, lets say I have two subnets/vlans that I need to route between (on two different L2 switches) and also I need them to be able to access the WAN. I need to add one to my ever growing lab. I haven't had the opportunity to play with any 元 switches so my knowledge is lacking in that area. Wouldn't this not only give me the ability to route between the Vlans but also aggregate ports for higher speeds AND give redundancy incase of link failures? So If I have one 48 port switch with three or 4 vlans on that ONE switch, I can use a router on a stick and then do an etherchannel from the switch back to my 2811. data or voice AND data), how much time they are staying on the local subnet, etc.It seems to me, that the router on a stick method would be much cheaper than to have to buy and put a 元 Switch into the distribution layer when I could have a 2800 router or better performing distribution and core work for me.Some routers (2811 with the appropriate Network Module) allow you to create Etherchannel Bundles on the routed/switch interfaces. But on to my question:Are router on a stick used in many production environments? I know a lot about this question depends on how may users are on the network, what kind of data they are doing (i.e. While I agree with this, it is also a lot more expensive to do it this way.
The book I am using to re-certify for my CCNA says that a router on a stick is a bad idea because of its single point of failure and that routing on the "backplane" with a 元 switch is a much better option. Just a quick question as to using a "router-on-a-stick" design.
