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?
