IPMP configuration and zones - how to?

Question

Hello all,
So, I've been thrown in at the deep end and have been given a brand new M4000 to get configured to host two zones. I have little zone experience and my last Solaris exposure was 7 !
Anyway, enough of the woe, this M4000 has two quad port NICs, and so, I'm going to configure two ports per subnet using IPMP and on top of the IPMP link, I will configure two v4 addresses and give one to one zone and one to the other.
My question is, how can this be best accomplished with regards to giving each zone a different address on the IPMP link.
IP addresses available = 10.221.91.2 (for zone1) and (10.221.91.3 for zone2)
So far, in the global zone I have
ipadm create-ip net2     <-----port 0 of NIC1
ipadm create-ip net6     <-----port 0 of NIC2
ipadm create-ipmp -i net2,net6 ipmp0
ipadm create-addr -T static -a 10.221.91.2/24 ipmp0/zone1
ipadm create-addr -T static -a 10.221.91.3/24 ipmp0/zone2
the output of ipmpstat -i and ipmpstat -a is all good. I can ping the addresses from external hosts.
So, how now to assign each address to the correct host. I assume I'm using shared-ip?
in the zonecfg, do I simply (as per [this documentation|http://docs.oracle.com/cd/E23824_01/html/821-1460/z.admin.task-54.html#z.admin.task-60] ):
zonecfg:zone1> add net
zonecfg:zone1:net> set address=10.221.91.2
zonecfg:zone1:net> set physical=net2
zonecfg:zone1:net> end
and what if I have many many addresses to configure per interface... for example zone1 and zone2 will also require 6 addresses on another subnet (221.206.29.0)... so how would that look in the zonecfg?
Is IPMP the correct way to be doing this? The client wants resilience above all, but these network connections are coming out of different switches thus LACP/Trunking is probably out of the question.
Many thanks for your thoughts... please let me know if you want more information
Solaris11 is a different beast altogether.

Thanks for the reply....
It still didn't work... but you pointed me in the right direction. I had to remove the addresses I had configured on ipmp0 and instead put them in the zonecfg. Makes sense really. Below I have detailed my steps as per your recommendation...
I had configured the zone as minimally as I could:
zonepath=/zones/zone1
ip-type=shared
net:
address: 10.221.91.2
physical=ipmp0
but after it is installed, I try and boot it and I get:
zone 'zone1': ipmp0:2: could not bring network interface up: address in use by zone 'global: Cannot assign the requested address
So, I changed the ip-type to exclusive and I got:
WARNING: skipping network interface 'ipmp0' which is used in the global zone.
zone 'zone1': failed to add network device
which was a bit of a shame.
So, finally, I removed the addresses from ipmp0
ipadm delete-addr ipmp0/zone1
ipadm delete-addr ipmp0/zone2
and set the address in zonecfg together with the physical=ipmp0 as per your recommendation and it seems to be working.
So, am I correct in taking away from this that if using IPMP in shared-ip zones, don't set the address in the global zone, but stick it in the zone config and everyone is happy?
I think this was the only way to achieve multiple IP addresses on one interface but over two ports?
Lastly, why oh why is the gateway address in netstat -rn coming up as the address of the host?
Anyway, thanks for your help.
