I have two router conected each other using fastethernet 0/0 on both and i cant reach the interface to be up/up state
the configuration i have in both interface is the fallowing:
R1
interface fastethernet 0/0
ip address 192.168.1.1 255.255.255.0
no shu
R2
interface fastethernet 0/0
ip address 192.168.1.2 255.255.255.0
no shu
I had used straight and crossover cable and none of them work, but if i conect a pc or a switch in that interface it work perfect, so is not a interface problem or a cable problem, is there something else sI need to configure to be able to conect 2 routers through ethernet cable?

Hello,
in theory, a crossover cable should work. Make sure you actually really have one: pins 1 and 3 and 2 and 6 should be reversed.
Also, try and hard code speed and duplex settings on both ports (speed 100/duplex full)..

Does it work on either interface of either router or just the one router? - You could also try defaulting the interfaces and re-configure them
default interface fa0/0
interface fa0/0
no shut
ip address x.x.x.x
sh controller fa0/0
sh ip interface fa0/0
sh interface fa0/0
