i know that switch will be enough good for it. This configuration is only for education. I dont want to use it everyday.

But why do you need a router there? A simple switch will do.

You will need:-

Choose address range for new subnet

10.1.1.0 255.255.255.0

Choose address for new router on existing subnet

192.168.0.254

router 1 ip route 10.1.1.0 255.255.255.0 192.168.0.254

router 2

int fa 4 ip address 192.168.0.254 255.255.255.0 no shut

int vlan 1

10.1.1.1 255.255.255.0 no shut

ip route 0.0.0.0 0.0.0.0 192.168.0.1

On 871 ports fa 0-3 default to be members of vlan 1.

I'm not sure if i understand you correctly. You wrote: ... router 1 ..... router 2 ...... Should i reconfigure router 1 also?

My actuall config on Cisco 871 is below.
