Hi Mike
The netmask is /24.

Thanks

This implies that you have three different subnets and you either have
three distinct cables going to the machine or you are using three
VLANs.

In the global zone you will have 10.10.30.1 in /etc/defaultrouter.

In zone1's zone configuration, you will have a network configured like
the following (assuming VLAN 10 tagged on on e1000g0):

zonecfg:zone1 info net
net:
address: 10.10.10.123/24
physical: e1000g1
defrouter: 10.10.10.1

In zone2's zone configuration, you will have something like (assuming
VLAN 20 tagged on e1000g0):

zonecfg:zone1 info net
net:
address: 10.10.20.123/24
physical: e1000g2
defrouter: 10.10.20.1


This could also work if they are all on a single 'data link' as seen by 
'dladm show-link', although I only do that in my play situations.

Hi Gurus

I need to setup zones as shown below.
Zone1: 10.10.10.X with default router 10.10.10.1
Zone2: 10.10.20.X with default router 10.10.20.1 And Global zone
10.10.30.X with default router 10.10.30.1

Is this achievable. As shown above, I need the zones to have a
separate default router than  the default router for the global zone.

I don't have the luxury of using dedicated ports to achieve this.
Any suggestions/workarounds are greatly appreciated.

What is the netmask?  That is, the story is completely different between:

10.10.10.x/16
10.10.20.x/16
10.10.30.x/16

And

10.10.10.x/24
10.10.20.x/24
10.10.30.x/24

If it is the second, then you are dealing with three distinct subnets
and life is much easier.   If you really only have one subnet, I'm not
sure there is a solution.
