Dear all gurus out there,
I am newbie to Linux and networking.
I have a Red hat linux that used as a Database machine, oracle.
I have 2 network cards that I wish to set to 192.168.0.10 and
192.168.0.11 respectively, the default gw is 192.168.0.1. The
connection of the two IPs coming from 2 different switches (still from
the same router).
My purpose is that : if one of the switches is down, my connection
still up with the other side.
I know switch is hardly "down", but i wish to have full redundancy.
What I did is, I jus set the 2 network cards with the two IPs and I
switch off one of the switches, "poof" the whole network
down..........so, how can it be done ?
Or any other alternatives ?
Thanks.
Google bonding network interfaces...
You need to have one ip address that is on both switches and will move
from a primary to a seconday NIC.
Intel had it's own IANS software on the older Linux versions but is now
supporting standard bonding. On the 2.4 the Intel stuff was nice but
required at least one Intel NIC per bonded pair.
