Inter-vlan Routing Question

[rkeeran]

Hello All

I am trying to set up inter-vlan routing without a router. I have a Catalyst 3560 that has 5 vlans. This switch Is connected to a ISP Modem. Intervlan routing is set up on the switch but I am stuck. I am unable to browse the internet from any of the vlans. I am able to ping 8.8.8.8 from the switch but not from the vlans. If there is a router present I can use NATing to fix this but trying to see if it is possible to do it without the need of a router.

Hello,

the short answer is: you need the router. The switch does not do NAT. You are better off doing a "router-on-a-stick" setup. If you don;t know how to use subinterfaces on the router, post the router config as well, so we can help you with the details...

[rkeeran]

Hi Georg

Thanks for the rapid response. I have a Cisco 2621xm and when I set up router on a stick, speeds are below 30 Mbps when I get connectivity. Is there a way to fine tune the performance of the network if router on a stick is set up?

[Georg Pauwen]

Hello,

the 2621XM is end of sale as of 2007, so you obviously have an ancient device there. Not sure how much that can be tuned, post the running config of the 2621XM. But actually, to be honest I think the router will be the bottleneck no matter what.

[rkeeran]

Hi Georg

I have setup up Router on a stick on my set up at home. Please see configs attached

[Joseph W. Doherty]

See attachment for performance of a 2621XM.

[rkeeran]

Hi Joseph

Thanks for the heads up. What can I expect from a Cisco 2811 router?

[Georg Pauwen]

Hello,

the 2811 is end of sale as of 2011. It won't be a big improvement.

What is your budget ? You might be better of just buying, depending on what you are willing to spend, a Cisco ISR 1111 (around 700 dollars) or just a 'cheap' ISP modem (around 100 to 200 dollars).

[rkeeran]

Hi Georg

Its for a small office space. Service provider is potentially going install a Hub 2000/3000 modem. Client wants to reduce costs as much as possible. Trying to exhaust my options before going with the only option available.

[Joseph W. Doherty · Accepted solution]

See attachments.

[rkeeran]

Thanks Joseph!

I really appreciate it. I have a bit more to reconsider. Thanks

Hello

As stated by @Georg Pauwen you will need a router for the network translation and also quite a good scalable one to accommodate the amount of users you may have.

I would personally look into meraki soho rtrs, however review the following selector to provide you with some idea on what would be applicable. -here
