ISIS IOS level

gibby1801

I am running a Cisco 3750 with IOS c3750-ipservicesk9-mz.122-25.SEC2.bin. When I try to enable "router isis" I get a message stating this protocol is not available. Does anyone know what level IOS supports ISIS?

Thanks!

You can find the information here

But the 3750 is a switch version and I don't think it supports ISIS even with the EMI image, maybe The metro ethernet version supports it but I don't think your version will run it. Check the feature navigator for more info.

I don't see IS-IS listed as a supported routing protocol in the 3750 documentation.

http://tools.cisco.com/ITDIT/CFN/jsp/index.jsp shows support for IS-IS in the METRO 3750 EMI images

It depends on the version of IOS. As far as I know, the only versions of IOS that support ISIS are the service provider editions. I just checked a 2600 with enterprise and it doesn't support it.
