First:
You override the first line with the second line. So in the end, all you 
accomplish is mark the interface up.
Second:
network in the first line should be netmask

You should delete the second line (an interface will be marked up if an IP 
address is assigned to it) and fix the netmask keyword.

You may want to read up on sh(1) how it treats variables.
