I was a little confused about this but I think we are talking about the same
thing. In your example here you have your default gateway set to your VIP.
In my configuration I am doing the same thing (on a single network) but it
is not working.
My routing table on my realservers looks like this:
Kernel IP routing table
Destination Gateway Genmask Flags MSS Window irtt
Iface
127.0.0.0 0.0.0.0 255.0.0.0 U 0 0 0 lo
0.0.0.0 VIP or DIP 0.0.0.0 UG 0 0 0
eth0
I think you are telling me to do what I have already set up and it is not
working for me but it's very possible that I am missing some piece of the
puzzle that I am not getting from your posts.
My LVS works fine (if I use the director's IP for a default gw) and my HA IP
address takeover works fine. The problem occurs when the backup has taken
over. If my realservers are using the directors IP as a gateway nothing
will work for obvious reasons. I have tried to use the VIP as the
realservers default gw but this will not work for the primary or backup lvs.
1. Should I be able to use the VIP as the realservers default gw?
2. If yes, what could I be doing wrong that is causing my problem?
3. If no, what can I use to reset my realserver default gw when the backup
takes over?
I'd really appreciatte it if someone could help me clear this up.

No, i am definitely not saying that you should switch, I am just saying that
the documentation of keepalived described very well the principals that you
should configure heartbeat with .
a sample of redundant active-active lvs directors setup with heartbeat :
on f1 :
external interface 200.200.200.1
internal interface 10.0.0.1
on f2 :
external interface 200.200.200.2
internal interface 10.0.0.2
haresources on both machines :
f1 10.0.0.253 200.200.200.3
f2 10.0.0.254 200.200.200.4
half of real servers have default gateway point to 10.0.0.253 , and the
other half to 10.0.0.254
half of the clients access the real servers with ip address 200.200.200.3,
and half with 200.200.200.4
if you don't need active active setup , just (in this config) i would have
in haresources :
f1 10.0.0.253 200.200.200.3
all real servers have as default gateway 10.0.0.253, and all clients would
access the cluster at 200.200.200.3
