RE: multi nic redundancy to increase availability

["O'Neill, Donald \(US - Deerfield\)" <dooneill deloitte com>]

Bonding two nic's to the same IP is an easy process.  This is taken from
the bonding.txt file. 

1) create a bond0 file in your /etc/sysconfig/network-scripts directory

DEVICE=bond0
IPADDR=192.168.1.1
NETMASK=255.255.255.0
NETWORK=192.168.1.0
BROADCAST=192.168.1.255
ONBOOT=yes
BOOTPROTO=none
USERCTL=no

2)add an entry into your /etc/modprobe.conf file

Alias bond0 bonding

3) Change your /etc/sysconfig/network-scripts/ifcfg-eth0 file to 
DEVICE=eth0
USERCTL=no
ONBOOT=yes
MASTER=bond0
SLAVE=yes
BOOTPROTO=none

4)Change your /etc/sysconfig/network-scripts/ifcfg-eth1 file to 
DEVICE=eth1
USERCTL=no
ONBOOT=yes
MASTER=bond0
SLAVE=yes
BOOTPROTO=none

Restart network

hi,

we have a dell pe 2650 and other dell servers, all
with two ether cards, running redhat EL AS3. i need to
make use of both cards so that the down time may be
reduced.

it seems that there are a few different ways to do so.
binding two cards to the same IP seems complicated. is
it possible to give each card different ip, but the
same domain name? i remembered something like each
card's IP must be on different subnet? but I want them
to be on the same subnet. any suggestions?

thanks
cheng
