That's interesting.
My boxes do not have /etc/defaultrouter. They do have two Ethernet ports
(the one for Nodebus and one for the Plant network) and in.routed is NOT
running.
Like I said, I've never tried /etc/defaultrouter because I was told long ago
that in.routed would startup.
I just took a look at one of my boxes. The /etc/rc2.d/S69inet startup script
has the lines that start in.routed commented out. We (Foxboro) must do this
as one of our configuration changes.
The lines that issue a /usr/sbin/route command are retained.
So, on an I/A Series AW/AP/WP, using /etc/defaultrouter does no harm.
Just be careful that you never start in.routed.

Alex,
It is one of those rare times, but I believe you need to be
corrected. Solaris will start in.routed and act like a router only when
multiple interfaces (le?, hme?, whatever) are defined and /etc/defaultrouter
does NOT exist.
If /etc/defaultrouter exists, a Solaris box will always send I.P.
packets to the "default route" device whenever it is trying to communicate
to devices on segments not directly connected to it.
I never do it myself or recommend to others using anything but the
standard Sun supplied mechanisms to configure any part of I.P. networking
for additional interfaces on a machine.

The problem with defaultrouter that it supposedly starts the Solaris
routing
software too. This is a bad thing since it would "publish" the
Nodebus IP
addresses.
I can't say that I've tested that myself, but if someone (Darryl?)
is using
it do a ps -ef | grep in.routed and see if it is running. If it is,
you
could be publishing a bunch of IP addresses that are not unique.

The Sun way is to add the entry for the router in /etc/hosts
112.113.1.1 router
Then create a file called /etc/defaultrouter with the word
'router'
in
it.
echo router >/etc/defaultrouter
When Solaris boots it will configure the default router for
you.
