Work Around 
The work around is to create an /etc/defaultrouter file, and
reboot all your systems, before setting up IPMP.  For example,
after I "echo 172.21.8.254 > /etc/defaultrouter" on all my
systems, and rebooted them, I did not see the IP_ADD_MEMBERSHIP
message after setting up IPMP.
Comments 
"Introduced in Release" and "Introduced in Build" have been set to match
the first integration of IPMP into Solaris.
