I'm looking for a way in RHL 5.1 to use two NICs on one host with two physical IP addresses and map them under one virtual IP address, i.e. NIC 1 10.10.10.1 NIC2 10.10.10.2 VIP 192.168.10.1

Basically I want either one of the NICs to ARP for the VIP. No load balancing required just HA.

in solaris this is called IPMP and is an onboard feature... i've never done this in linux. but this should be a driver issue. so have a look at the homepage of the vendor of your nics...

hi wschmied,

i'm not really sure what you were up to? was it an L3 IP mapping or purely L2 NIC bonding?

if you want an L3 IP mapping - IMHO AFAIK - you have to create an LVS (even though what you need was only an HA).

just for a simplicity :
this link would be a nice start.

or if you want a pure L2 NIC bonding :

HTH.
