VLAN Question

I have always setup VLAN's using a Cisco Switch and Router, however I'm hearing that it's possible to setup a 3560 Switch with multiple VLAN's and also route between the VLAN's.



Is this true or do I still need a Cisco Router?



My guess is that I still need the router.



Thanks in advance!



Just as a followup, I see that some switches will do L3 routing and a separate module is needed. Would this be a software module to allow "ip enable routing"?

Currently if I enter "ip enable routing" it's not a valid command on the 3560.

Thanks again:)

I think that the 3560 switch only allows one active layer3 vlan interface, usually used for management so you would have to trunk vlans to a router to route between them.

The command is 'ip routing', not 'ip enable routing'

Chris.

You can set up vlans on just about any Cisco switch, and can "switch" or route between them (intra-vlan routing)....

depending on the IOS image. The command to enable routing in IOS is ip routing.

Brain stink...I meant "ip routing":(

Seems I need to setup for intra-vlan routing. The link above was broke, or else required special access, however I did find this:

Seems like this is what I need to do.

Thanks much Lovejoy!!!

That's for older Catalyst switches running CatOS on the switch and IOS on the RSM. Not really relevant to your switch. Completely different product.

Thanks Chris...really appreciate the previous "one active layer3" response too:)

He is right. That is an oldie..... Try this one :
