6307539 RFE: Invalid network address causes zone boot failure
5041214 Allow IPMP configuration with zones
5005887 RFE: zoneadmd should support plumbing an interface via DHCP

6218378 zoneadmd doesn't set the netmask for non-loopback addresses hosted on lo0
4963280 zones: need to virtualize the IPv6 default address selection mechanism

5023347 zones don't work well with network routes other than default
4963372 investigate whether global zone can act as a router for local zones
