Network load balancing Ethernet on iSeries

Hi All,
At the moment all of my ethernet cards in the iSeries have separate ip
adresses and hostnames (in the dns). With a alias and the round robin
principle (dns) there ais some load balancing. But with a failed
adapter the dns does not know of this problem. Anyone experienced with
VirtualIp and proxy ARP?, or is a distributed director a better
solution. What I want is a tranparent and balanced set of eth.
adapters,1 dns hostname/ip-adres and no aliases. What about a network
dispatcher? Is the VirtualIp adres propagated into the network or just
local internally in the machine

I just implemented *virtual IP and Proxy ARP.

ending one (or the other) physical interface did not end any connections
from the clients.

When you start an IP connection from the iSeries you see one of the
Physical interfaces in netstat.

HTH,
Ad.

Virtual IP is pretty easy to set up...
The Virutal IP is propogated into the network.. other systems ARP caches
will reflect this IP address with the mac-address of the real adapter.

I don't have experience with a system with multiple NICs.
