Beginner setting up solaris 10 container and having network card problems

Question

Hi I am just learning about solaris containers and am having an issue of getting my new zone to be seen on the network.
I have installed the global zone server name GPSAPP02 network address of 192.168.200.45 works fine.
I created :-
a pool called "ellipse-pool" using pooladm/poolcfg
a zone called "ellipse-zone" using zoneadm/zonecfg
I used the followijng commands...
zoneadm list -cv      
zonecfg -z ellipse-zone
create               --
set zonepath=/zfspool/zones/ellipse-zone
set autoboot=true     
     add net     
set address=192.168.200.46/24
set physical=eri0     
set defrouter=192.168.200.254
end                
set pool=ellipse-pool     
verify
commit
exit
The output from the "zonecfg -z ellipse-zone info" command is below:-
zonename: ellipse-zone
zonepath: /zfspool/zones/ellipse-zone
brand: native
autoboot: true
bootargs:
pool: ellipse-pool
limitpriv:
scheduling-class:
ip-type: shared
inherit-pkg-dir:
dir: /lib
inherit-pkg-dir:
dir: /platform
inherit-pkg-dir:
dir: /sbin
inherit-pkg-dir:
dir: /usr
net:
address: 192.168.200.46/24
physical: eri0
defrouter not specified
I then installed the zone and rebooted using zoneadm.
I can login to the zone and setup the timezone and terminal etc.
I gave this a hostname of GPSEL01 as this is what I want it to be known as on the network.
So far so good but from the network I cannot ping the IP address I assigned to the zone 192.168.200.46
What have I missed or what should I check to troubleshoot this?
I ran a ifconfig -a and received the following information...
ifconfig -a
lo0:1: flags=2001000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4,VIRTUAL> mtu 8232 index 1
inet 127.0.0.1 netmask ff000000
# ifconfig lo0:1 192.168.200.46 netmask 255.255.255.0 up
ifconfig: SIOCSLIFNETMASK: lo0:1: permission denied

Hi
I notice in your output from ifconfig -a in the global zone that the NIC card is nge1.
However in your zoneconfig you have set the NIC card to eri0 (physical = eri0). I cannot see this NIC card in your ifconfig -a.
When a zones is of IP-type shared-ip it needs to use a network interface that is already plumbed into the global zone. In your case you need to change the NIC in your zone config to nge1 :
zonecfg -z ellipse-zone
select net address=192.168.200.46
set physical=nge1
end
exit
Then reboot your zone.
A couple of other minor comments.
1) As it appears the zone is on the same subnet as the global zone, if the global zone already has the default route of 192.168.200.254 setup you don't need to specify it in the zone config. You are most likely to use the defrouter parameter if the zone was on a different subnet to the global zone (but shared the same physical NIC).
2) You have specified the netmask in the address field which is fine. But again this should not be necessary as long as your /etc/netmasks file is correct in the global zone.
Hope this helps
