virtual_ipaddress {
192.168.1.20
}
use_vmac
vmac_xmit_base
}
If the last two lines (use_vmac and vmac_xmit_base) communication with
192.168.1.20 (the virtual_ipaddress) fails, if they are commented out
communication works. No firewall is being used on the system. rfc3768
section 7.3 provides the specifics about virtual mac addresses. The
keepalived implementation creates an additional NIC and assigns the
virtual_ipaddress to it if the vmac configuration is used. If they
aren't used and a failover occurs then connectivity is lost to the
virtual IP address until arp cache timeout occurs on client devices and
the different mac address is learned.
I have a suspicion that this is systemd related. The reason is that,
when installed on Devuan [Devuan GNU/Linux 2.1 (ascii) - a non-systemd
distribution of Debian] it works. I even de-installed the Ubuntu
version, downloaded the keepalived.deb (1:1.3.2-1) on the Devuan system,
transferred it to the Ubuntu system, installed it and resolved
dependencies, used the same keepalived.conf from Devuan changing only
the interface name and started keepalived (keepalived on Devuan was shut
down for the test). I got the same results as with the Ubuntu version.
This problem also existed on Ubuntu 16.04 LTs which used an even older
version of keepalived.
