Check that multiple, non-redundant NICs are not connected to the same network. The following configuration example shows that two activated NICs are connected to the same network. In this case, OS routing tables overlap, so communications may not be performed correctly. To avoid this, connect to a different network.
Confirmation method
Use a command such as the ip route command to check that the same network address is not set for a different device. In the following execution example, different devices have been set to the same network. Therefore, you need to change the network address of the either of the two.
# ip route 192.168.10.0/24 dev eth0 proto kernel scope link src 192.168.10.20 192.168.10.0/24 dev sha0 proto kernel scope link src 192.168.10.10 |
