**********************************************************************

FastEthernet0/0 did Not UP yet because of Another Router did Setup yet

**********************************************************************

*********** Check Interface fast Ethernet 0/0 Detail *************

LAB_A#sh int fast 0/0

FastEthernet0/0 is up, line protocol is down
