Hi Brian,
I've found out the problem!!
Thanks!
The problem is with pim6dd running on other bsd machines in our network. Once I
disabled pim6dd on the gateway router connecting the solaris 8 machine, the error mesg
stops.
here's the snoop results before and after disabling pim6dd
-- BEFORE (with PIM6DD running) --

Note: very quiet! just ripng and router advs ;)
When i check SUN's IPv6 website, solaris 8 doesn't have support for pim6dd yet.
http://www.sun.com/solaris/ds/ds-ipv6networking/
so, that's the problem!
