T4-4 no network traffic even plumb up the interface

I setup the network interface to zone, the network interface is up, but no traffic can reach it. Is that any steps need to set

Local Zone

# ifconfig -a
lo0: flags=2001000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4,VIRTUAL> mtu 8232 index 1
        inet 127.0.0.1 netmask ff000000
igb1: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 2
        inet 202.45.35.71 netmask ffffff80 broadcast 202.45.35.127
        ether 0:21:28:fa:d8:cb

Globalzone 

# zonecfg -z zone03 export
create -b
set zonepath=/zonepool/zone03
set autoboot=true
set ip-type=exclusive
add net
set physical=igb1
end
add capped-memory
set physical=80G
end
add rctl
set name=zone.cpu-cap
add value (priv=privileged,limit=400,action=deny)
