Multihome routing on solaris zones

If you intended to install Solaris zones with different sub networks, then you need to add the new gateway for each sub net to /etc/defaultrouter of the parent global zone line by line.

For example:

# cat /etc/defaultrouter
124.141.66.51
124.141.65.41
#

editing /etc/defaultroute inside non-global zone has no effect.
Also, manually adding default route by route command from non global zone will generate "not owner" error message.
