Description 
I am testing s9_51 with ipmp configured. I have done both 32 and 64 bit modes.
I have used it as the primary and non-primary network. I am doing NGDR cmds
addboard and deleteboard. 

Latest testing setup:

xf6-b2:
xf6-b2# more hostname.qfe4
192.168.95.54 netmask + broadcast + group testb2 up addif 192.168.95.14 deprecated -failover netmask + broadcast + up
xf6-b2# more hostname.qfe8
192.168.95.56 netmask + broadcast + group testb2 up addif 192.168.95.21 deprecated -failover netmask + broadcast + up
xf6-b2# more hostname.qfe0
xf6-b2

ifconfig output before any dr/ops:

Or they would come up as most all qfe8 interfaces depending on which
brd is dr'd out of the domain.

The other domain tested was xf6-b13 - this domain was set up a little 
differently but with the same result. This had the primary under ipmp
and the qfe was blacklisted on one of the brds. (The primary brd)
Does not seem to matter how it is set up. It is also not dependent on
any sort of timing between the dr/ops.
