The example ucarp config for a virtual IP for Debian/Ubuntu is in
/usr/share/doc/ucarp/README.Debian and is as follows:
The recommended method for configuring ucarp is via /etc/network/interfaces. For example: iface eth0 inet static address 10.0.0.2 netmask 255.255.255.0 ucarp-vid 3 ucarp-vip 10.0.0.1 ucarp-password 16charsatmost ucarp-advskew 0 ucarp-advbase 1 ucarp-master yes iface eth0:ucarp inet static address 10.0.0.1 netmask 255.255.255.255
In the document it isn't clear how or if it is possible to configure multiple VIPs on a single interface with this configuration method. Does anyone know if this is possible?
