Problem with Multiple network cards on the same subnet.

I am having problems configuring two network cards that are on the same
subnet. Here are my configuration files.

[root localhost sysconfig]# cat network
NETWORKING=yes
HOSTNAME=localhost.localdomain

[root localhost network-scripts]# cat ifcfg-eth0
DEVICE=eth0
BOOTPROTO=static
IPADDR=192.168.2.101
NETMASK=255.255.255.0
GATEWAY=192.168.2.1

[root localhost network-scripts]# cat ifcfg-eth1
DEVICE=eth1
BOOTPROTO=static
IPADDR=192.168.2.102
NETMASK=255.255.255.0
GATEWAY=192.168.2.1

When I run route, both routes are created on the eth1 interface.

[root localhost network-scripts]# route
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use
Iface
192.168.2.0 * 255.255.255.0 U 0 0 0 eth1
192.168.2.0 * 255.255.255.0 U 0 0 0 eth1
127.0.0.0 * 255.0.0.0 U 0 0 0 lo
default 192.168.2.1 0.0.0.0 UG 0 0 0 eth0

I would expect a route to be added for each network card to the
192.168.2.0 network.

The problem I have is when one network connection is down, both links
stop working. I expect the routing table has something to do with this
problem. Can anyone tell me if this routing table was created
correctly, and if it was not, how to fix the problem?

The reason we are trying to configure two network cards is so we can
keep the network traffic from backups seperate from regular system use.
Is there a better way to solve this problem? We do not have multiple
subnets available to move one IP address.
