I am trying to get LVS-DR working in a dual home setup.
Everything seems to be working fine for VIP1 but requests are timing out on
VIP2. I can see the requests being distributed to the real server by LVS but
the response never reaches the user as if arp tables was not configured
correctly. Any ideas?
VIP1 = 10.10.1.180
VIP2 = 10.10.2.38 (Not enabled in DNS yet)
On the director:
TCP 10.10.1.180:80 rr
-> 10.10.1.210:80 Route 1 18 636
-> 10.10.1.203:80 Route 1 19 637
TCP 10.10.2.38:80 rr
-> 10.10.2.36:80 Route 1 0 5
-> 10.10.2.37:80 Route 1 0 6
On the realserver:
