ifup eth0 failed in Ubuntu 11.10 and Ubuntu 10.04.3

ifup eth0 failed to bring up eth0
First, I have set static ip using the below commands:
Commands:
ifdown eth0
ifconfig eth0 X.X.X.X netmask 255.255.252.0 up
route add default gw X.X.X.X
I was successful in setting up static ip X.X.X.X and I could see the same in the output of command "ifconfig".
Now I am trying to revert network back to dhcp using the below commands:
Commands:
ifdown eth0
ifup eth0
Output :
RTNETLINK answers: File exists
ssh stop/waiting
ssh start/running, process 1524
ifup eth0, failed to bring back dhcp.
Contents of /etc/network/interfaces
root@bdhcp396:~# cat /etc/network/interfaces
# The loopback network interface

iface eth0 inet dhcp
Is this a bug in Ubuntu 11.10/10.04.3?
