Keepalived can do this by combining the nopreempt option and the BACKUP state on the both nodes:
Prevent VRRP Master from becoming Master once it has failed
Prevent master to fall back to master after failure
How about the UCARP?
Name : ucarp
Arch : x86_64
Version : 1.5.2
Release : 1.el5.rf
Size : 81 k
Repo : installed
Summary : Common Address Redundancy Protocol (CARP) for Unix
URL : http://www.ucarp.org/
License : BSD
Description: UCARP allows a couple of hosts to share common virtual IP addresses in order
: to provide automatic failover. It is a portable userland implementation of the
: secure and patent-free Common Address Redundancy Protocol (CARP, OpenBSD's
: alternative to the patents-bloated VRRP).
: Strong points of the CARP protocol are: very low overhead, cryptographically
: signed messages, interoperability between different operating systems and no
: need for any dedicated extra network link between redundant hosts.
If I don't use the --preempt option and set the --advskew to the same value, both nodes become master.
