cisco 1603 router one ethernet interface

[b.koelmans]

Hi,

As I am new here I will introduce in the best way, I will ask a very easy question:

with a 1603 router with one ethernet interface is it possible to seperate two networks (192.168.1.0 and 192.168.2.0)? I only see that happening with another (e1) interface or with dial up or another router.

Am I right?

You can separate the two networks (192.168.1.0 and 192.168.2.0) using a 1603 router by creating 2 subinterfaces on the ethernet, e0, interface. You could setup e0.1 and e0.2 and assign 192.168.1.0 to e0.1 and 192.168.2.0 to e0.2.

Using sub-interfaces will not work. The easiest is to configure one primary IP and one secondary IP address on the ethernet interface.

Thanks guys for your reply. A very logical question to both of you: how can I try them out? Which means: could you give me some hints/commands?

Thanks in advance!

I worked the idea of fvanderb out and it works! Primary and Secondary ip addresses can solve this matter. With the adding of ip addresses to the subinterface e0.1 it received an error: only allowed if that subinterface is configured as part of an IEE 802.10 or ISL VLAN.....
