Hi all,
I am configuring a 2801 router . I set up ip address on the interface Fa 0/0 and 'no shutdown' command. But, after a restart , the interface is changing to down again!
What I must do to ?
Thanks in advanced!

is it just down or admin down? if it's just down then it's down because there's no live ethernet connection, is it plugged into anything?

This is admin down ! and is plugged into a switch .

If you do "show version" what does it say for configuration register, if it says something like 0xNN4N (where N is any number), then do these:
config t
config-register 0x2102
int fas0/0
no shut
exit
exit
write mem
reload

You must save the configuration.
write mem
Or
copy running-config startup-config
