Dobry den, zkousim na packet traceru nakonfigurovat router, ale nak mi to nejde, hazi mi to porad jednu a tu samou chybu

mam jeden router a na nem 2 PC, prvni PC router v pohode vezme, ale pri druhem mi to porad hazi:
192.168.1.0 overlaps with fastethernet 0/0


1. PC - 192.168.1.10 / 255.255.255.0 - fastethernet 0/0
2. PC - 192.168.1.11 / 255.255.255.0 - fastethernet 0/1
vychozi brana 192.168.1.1 (u obou)


postup: 1. PC
enable
configure terminal
interface fastethernet 0/0
ip address 192.168.1.10 255.255.255.0
no shutdown

1. PC funguje

postup: 2. PC
vratim se "exit"
interface fastethernet 0/1
ip address 192.168.1.11 255.255.255.0
a hodi mi to prave: 192.168.1.0 overlaps with fastethernet 0/0
