[OpenIndiana-discuss] network errors

[Jonathan Adams]

I generally use ip-type=exclusive all the time now, mainly because I'm fed
up with all the "default" route issues.

You can set up all the interfaces the same way you did in Solaris 10, just
create a vnic in the parent and use physical:default in the zone instead of
nwam.

dladm create-vnic -l nge0 <zone name>0

Then add the net physical=<zone name>0 to the zone set ip-type to exclusive
and boot the zone! ☺

Might be worth a go.
