[CentOS] routing multiple network cards on a single subnet

Frank,

I think the best way is to create bonding on eth1-eth2 and create an alias on this bond interface.
If you need to use the two interfaces in same time, you can use round robin parameter on the bonding interface. 

If you need help on bonding you can use this howto : http://www.generationip.com/documentation/system-documentation/65-bonding-or-teaming-for-redhat-server

Frank,

i know this has been addressed on the list a few times recently yet i dont
know if that will give you a solution.

ummm, why do the two different networks need an IP on the same subnet ?

can you just bond and bridge and have the same ip on both or ???

is this a redundancy thing?
