Two buildings split... keep all traffic to the large switch?

[cpals]

We currently brought up a second building at one of our locations and had help from our vendor in setting everything up, but I changed it after a while. We have a Cisco 6509 at the first location and initially they set it up so that both buildings were on the same VLAN, but I started running out of IPs so I split the second building into it's on VLAN for the data side. Everything is running back to the 6509 for L3 connectivity, but I'm wondering if that's the best way...

I just thought about this tonight and was wondering if I should turn on the L3 capability of the 3750 being used in the second building and use that instead of having all the traffic going out to the 6509 first for routing?

They're connected via fiber so I don't think it matters 'that' much, but I wasn't sure if it may help a little.

Oh, and all the switches are 3750 except for the core, which is the 6509.

Thanks.

If building 2 is fine on it's own single vlan, then i would think you're fine leaving the routing on the 6509. I would be more interested in QoS settings on the 3750's. It all depends on the performance you need now and in the future as well as the administarive overhead you're willing to allocate to any new changes. But if everything is fine right now, why bother with it? Don't try to do something you don't need. It'll save you some headaches 🙂

Layer3 is good. Layer2 connectivity is bad. Broadcast domains and spanning-tree are bad. You know what you need to do and it wouldn't take you but 10 minutes to make it so.

I would enable L3 on the 3750
