This statement confuses me because if I refer to a ip on the local node and
then run ipvsadm I always get something like:
IP Virtual Server version 1.2.1 (size=4096)
Prot LocalAddress:Port Scheduler Flags
-> RemoteAddress:Port Forward Weight ActiveConn InActConn
TCP vip-eml-302 rr
-> 172.16.3.11:smtp Masq 1 0 0
-> 172.16.3.12:smtp Local 1 0 0
172.16.3.12 is a ip on the local node and always seems to get flagged as Local.
So how do I avoid local node if the masq ip is on the local node?

The references that I can find don't qualify low loading either, but I would
assume that 10% resource consumption due to lvs and the rest remaining for
applications would be a reasonable assumption. If I can get it to work I would
be happy to share the performance data with the list (as long as I can get
permission from my employer). Modern machines are much more power these days.
It seems a bit wasteful to use a pair of hp dl360 g7s for a little lvs
for two mail servers that do less than 100k mail messages a day.

Ok the RIPs are all different (I sort of assumed that would be taken as given)
We have 2 VIPs on the Primary network and another two on the secondary.
VIP1 and VIP1s are taken as a pair as are VIP2 and VIP2s.
