solaris zones on different subnets

Greetings,

Having an issue with a multihomed global zone hosting zones on different subnets.
The issue is with the dev zone that is hosted on the non-default network.
Any help, other than going to exclusive IP, as I have one card for admin ntwk for both zones, would be appreciated.

Scenario details:

Global Zone (GZ) running Solaris 10 08/07.
NICs:
- ce0 used for admin network - virtual to each zone
- ce1 used for cluster heartbeat
e1000g0 - main NIC on Prod subnet - virtual to prod zone
e1000g1 - NIC plummed for Dev subnet - virtual to dev zone

i am able to get to my NIS server, on different subnet from both interfaces on GZ

i am not able to get to the NIS server from the dev zone.

Code:
 
$ zoneadm list -cv
  ID NAME             STATUS     PATH                           BRAND    IP

After many attempts with different varations, came up with a working repeatable solution.
Add second default route to /etc/defaultrouter:

#Production network
x.0.224.1
#Development network
x.0.228.1
