I think the 169.254.0.0/16 subnet is used for autoconfiguration ip addresses. Which are addresses that are self assigned after verifying that no one else is using it by sending out an arp ping (for instance, in case when the dhcp server is not giving out an address).
You should not use them when statistically assigning an ip address.
Oracle is using ip addresses in this range for the private network as part of the high available ip address (HAIP) functionality (which is also the reason multicast's must be allowed between the different nodes).

Subject: Re: RAC private network IP's - 169.254.x.x
Hi,
I am installing RAC on a new server(11.2.0.3 on RHEL 5.8). I have got the
error below.
Cause - Installer has detected that network interface bond0 does not
maintain connectivity on all cluster nodes. Action - Ensure that the chosen
interface has been configured across all cluster nodes. Additional
Information:
The work directory "/tmp/" cannot be used on any of the nodes Summary of
the failed nodes nodedb01 - The work directory "/tmp/" cannot be used on
node "nodedb01" nodedb02 - The work directory "/tmp/" cannot be used on
node "nodedb02"
i have disabled the bonding now. Even then, I am getting the same error on interface eth0 for public & eth2 for private.. I have eth0 for public & eth2 for private on both nodes..
can anybody throw some light on why I am getting the above error?
Thanks
krishna
