Hello,
I am trying to set up LVS with DR on the following setup:
1 load balancer router: 194.145.200.86 : Ubuntu 9.10
2 servers:
server1: 194.145.200.17 - CentOS 5.4
server2: 194.145.200.171 - CentoS 5.4
1 extra ip used for VIP on the load balancer:
194.145.200.87
I have done the following:
On the loadbalancer:
Configured 2 ip-adresses (also the VIP):
eth0 Link encap:Ethernet HWaddr 00:16:3e:0c:f6:ce
inet addr:194.145.200.86 Bcast:194.145.200.255
Mask:255.255.255.0
eth0:0 Link encap:Ethernet HWaddr 00:16:3e:0c:f6:ce
inet addr:194.145.200.87 Bcast:194.145.200.255
Mask:255.255.255.0
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
Interrupt:14
/etc/ha.d/ldirectord.cf:

real=194.145.200.17:25 gate
real=194.145.200.171:25 gate

On the real servers:
configured an lo:0 device:
lo:0 Link encap:Local Loopback
inet addr:194.145.200.87 Mask:255.255.255.255
UP LOOPBACK RUNNING MTU:16436 Metric:1
/etc/sysctl.conf:
net.ipv4.ip_forward = 1
net.ipv4.conf.all.arp_ignore = 1
net.ipv4.conf.eth0.arp_ignore = 1
net.ipv4.conf.all.arp_announce = 2
net.ipv4.conf.eth0.arp_announce = 2
My issue:
I can connect to port 25 on the VIP, but:
-i always connect to server2
-when I take server2 down, I don't get connected to server1 (no route to
host) when I put server2 back in the pool I still get the no route to
host message:
michiel@wmichiele:~$ telnet 194.145.200.87 25
