sparc64 ipv6 query???

[Marco S Hyman <marc@snafu.org>]

I don't know if this is a real problem or just a local config issue.
The set-up is this:
                     
                                           3ffe:b80:fc:1::
                                           _______________
                                          |               |
	sparc		sparc64		i386a		i386b
	  |_______________|_______________|

	            3ffe:b80:fc:0::

sparc hostname.le0:			sparc64 hostname.gem0:
inet sparc 255.255.255.248 NONE		inet sparc64 255.255.255.248 NONE
inet6 alias sparc			inet6 alias sparc64

/etc/hosts on both machines are identical and contain the ipv6 addresses.
sparc is running named.  sparc64 uses sparc as a nameserver.  rtsold is
not used on either system.

The issue is this: after reboot sparc has an inet6 default link-local
route to i386a.

  default     fe80::2c0:4fff:fea0:9c05%le0   UG          0       47   1280   le0

It can ping6 i386b.  sparc64, on the other hand, doesn't have an inet6
default route and can not ping6 i386b until a route is added.

Where does sparc get its default route?  Why doesn't sparc64 get the
same route?

Problem, or cluelessness on this end?
