RE: Two Network cards for redundancy

Additional info...

You can set up outgoing load balancing using duplicate routes:

Subject: Two Network cards for redundancy

Hi all,

The 520 we've got came with two ethernet cards, and as I 
understand they 
were configured so that they both worked with the same IP 
address. This 
to introduce redundancy in case one failed (and perhaps to spread the 
load?). Then, when we restored our old system onto the 520, 
the network 
config got broken and I just set it up with one network card.

I'm going to have a go tomorrow at setting up the dual-card option 
tomorrow, but I can't work out how. I guess that you give 
each ethernet 
line it's own TCP/IP interface with a unique IP address, but I can't 
find where to specify the third IP address - the IP address you want 
both cards to 'pretend' to be. Can anyone help?

Also, we have some fairly fancy HP switches - do I need to configure 
them so that they know about this special setup?

Cheers

Guy
