#6 Virtual IP is not reachable in keepalived

[shunmugaraj]

Hi,

I need a favor, i have setup 2 node cluster using keepalived, i am not able to reach Virtual IP from different subnet.

My conf file is as follows:

! Configuration File for keepalived

vrrp_instance VI_1 {
state MASTER
interface eth0
virtual_router_id 51
priority 150
advert_int 1
authentication {
auth_type PASS
auth_pass 1111
}
virtual_ipaddress {
172.19.9.209 brd 172.19.9.255 dev eth0
}
}

My sysctl has following lines:

net.ipv4.ip_forward = 1
net.ipv4.conf.default.rp_filter = 1
net.ipv4.conf.default.accept_source_route = 0
kernel.sysrq = 0
kernel.core_uses_pid = 1
net.ipv4.tcp_syncookies = 1
kernel.msgmnb = 65536
kernel.msgmax = 65536
kernel.shmmax = 4294967295
kernel.shmall = 268435456
vm.overcommit_memory = 2
vm.overcommit_ratio = 80
net.ipv4.conf.lo.arp_ignore = 1
net.ipv4.conf.lo.arp_announce = 2
net.ipv4.conf.eth0.arp_ignore = 1
net.ipv4.conf.eth0.arp_announce = 2
net.ipv4.conf.all.arp_ignore = 1
net.ipv4.conf.all.arp_announce = 2

I have two setups one with VM and aonther with non VM. In Vm i am not able to reach the virtual ip at all.

But in the case of non VM virtual ip is reachable for sometime, after that i am not able to reach.

i am using latest keepalived(1.2.16) package.

Thanks a lot.

Looks like ARP request is coming to the Master node, but master is not responding to the APR request.

when i sent arping -U 172.19.9.210 -I eth0, virtual ip is reachable.

ip addr list:

-bash-3.2# ip addr list eth0
