Network Interface Card (NIC) bonding, also known as
NIC teaming and
trunking, is an important concept to understand and implement in any environment where high availability is of concern. Using this feature, a server administrator can ensure their machine will continue to be accessible in the event of a NIC failure, cable disconnection or other issue with one of the NICs.
If you run Linux servers, you can configure your Operating System to use multiple NICs in a team using the procedure below.
1. Create a bond0 configuration file
Red Hat Linux stores network configuration in the /etc/sysconfig/network-scr
ipts/ directory. First, you need to create bond0 config file:
As you can see, we now have one ip for both NICs in the form of bond0. If u want to test this method and ensure it will work when a NIC fails or is disconnected, simply use this command to shutdown one NIC - simulating a NIC failure.
#ifconfig eth1 down
Then, ping the IP given to the bond. You should receive a reply to your ping even after shutting down the second NIC. This is what redundancy is all about!
lol this not my site and i never ever went to that cant prove that though!!
do whatever you think appropriate......... enough said!
Do I just add it to the bond0 config file as GATEWAY=xxx.xxx.xxx.xxx?
