how to determine if a router is configured to process IPv4

[axfalk]

Can someone please tell me a way to tell if a Cisco router is configured to process IPv4?

Thanks.

We do it by default if IP routing is enabled(again this is by default)

All routers come default with ipv4 routing enabled. unless you disable using the command "no ip routing". To enable it, use command "ip routing"

Thanks for your response. So, it's "all" or "nothing", there is no granularity in disabling just ipv4 and leaving the rest of routing intact?

Thanks again.

I dont understand what you mean by "the rest of the routing". When you disable ip routing (using command no ip routing), router will not route any packets at all. You will need to enable bridging on the router, if you want the router to pass any traffic at all.

You could be routing IPX! I believe that is what he was asking.

[axfalk]

Sorry, what I meant was that besides IP, there are other protocols that a router can route. By using "no ip routing" command, do you disable only IP protocol or all of them?

Thanks.

Disabling IP routing disables only routing of IP. Other protocols such as IPX or any others are not affected at all.
