Why do you want to do that? It all works, right? Most important for the
routing table are the networks: which network to which ethernet card. 
If you change /etc/network/interfaces everything is handled correcly:

iface eth0 inet static
	address 192.168.0.1
	netmask 255.255.255.0
	network 192.168.0.0
	broadcast 192.168.0.255
#	gateway 192.168.0.3	#you can use a gateway if, for example,
192.168.0.3 is configured as ip-masquerade, so you can share your internet
connection


Now you can do a simple
# ifup eth0 
to initialize the ethernet card and
# ifdown eth0
to shut it down.

The routing table should also be fine for common use. (if you have complex
server configurations you may want to change something here).
