add a NIC to a running zone

# zonecfg -z zone1
zonecfg:slabzone1> add net
zonecfg:slabzone1:net> set address=XXX.XXX.XX.XXX
zonecfg:slabzone1:net> set physical=bge0
zonecfg:slabzone1:net> end
zonecfg:slabzone1> verify
zonecfg:slabzone1> commit
zonecfg:slabzone1> exit

Now we have to manually add a new interface to the running zone. Do this from the global zone as well

# ifconfig bge0 addif XXX.XXX.XX.XXX netmask XXX.XXX.X.X zone zone1 up

Created new logical interface bge0:3

Note: The ‘addif’ tells ifconfig to create a logical interface using the next available.

# ifconfig -a
lo0:1: flags=2001000849<up,loopback,running,multicast,ipv4,virtual> mtu 8232 index 1 inet 127.0.0.1 netmask ff000000
bge0:1: flags=1000843<up,broadcast,running,multicast,ipv4> mtu 1500 index 2 inet XXX.XXX.XX.XXX netmask ffffff00 broadcast XXX.XXX.XX.XXX
bge0:3: flags=1000843<up,broadcast,running,multicast,ipv4> mtu 1500 index 2 inet XXX.XXX.XX.XXX netmask ffffff00 broadcast XXX.XXX.XX.XXX

That’s it! you’re done.
