Solaris zones : How to set netmasks

Question : How to set certain netmask for a non global zone ?

Answer :
To define a certain netmask for a non global zone, use zonecfg command. The network address is one of:

1. a valid IPv4 address, optionally followed by “/” and a prefix length.
2. a valid IPv6 address, which must be followed by “/” and a prefix length.

Steps to follow
1. On the global zone, enter the zone configuration mode :

global_zone # zonecfg -z zone01
       zonecfg:zone01> add net
       zonecfg:zone01:net> set address=192.168.0.10/24
       zonecfg:zone01:net> set physical=eri0
       zonecfg:zone01:net> end
       zonecfg:zone01> exit

2. Verify the zone configuration :

global_zone # zonecfg -z zone02 info

3. To check and verify the settings you can use ifconfig within the non global zone :

zone01 # ifconfig -a
