crossbow discuss - Nov 2007 - help configuring a ce trunk for use by nonglobal zones

I am trying to configure a V890 to have a management port on 1 network 
using the onboard eri and 2 nonglobal zones each using a ce port on 
another network.  Do the the constraint of the ce NIC not being GLDv3, I 
have created a trunk consisting of ce0 and ce1 in the global zone.  This 
should create a fat pipe in the global zone which both nonglobal zones 
can effectively share.  Because I don''t want the global zone to have 
it''s own IP addr on this second network, I have added a startup script 
(S98xxx) which simply plumbs the trunk head.  When zone boots, the zone 
IP is established (Shared IP) and all is well - so far ...

The problem is that the nonglobal zones needs a default route to work.  
I tried putting a route add default script in a S99xxx file hoping that 
it would be picked up after the the zone boots but no joy.  I can 
manually add the route add default command but how or where can I get it 
into the system startup?

Hi Skip,
I have a similar setup,

I solved this by bringing the interface up with an valid address from a
local zone first, then add the default route for this address and
afterwards assigning the address 0.0.0.0


# temporarily assigns an address so we can add the default route
ifconfig ce3 <LocalZoneIP>/27 deprecated

route add default <LocalZoneDefaultRoute>
# remove the address again
ifconfig ce3 0.0.0.0


So I end up with an interface with more than one default route, but the
global zone does not use it at all, and each local zone has only one
valid default route.

Thanks Fritz!

That sounds like it will work perfectly!  I''ll try it today.  Where did
you put theses commands, ie. rc2.d/S99xxx or rc3.d/S99xxx ?
