Can any one explain me Shared-IP and Exclusive IP ??
Hi All,

I want to know what is shared-IP and exclusive-IP while configuring zone?

How the global zone and non-global communicate with each other?

When I do ifconfig -a on my machine it shows below output

My doubt is they are physical and virtual interfaces in below output what is physical interface and what is virtual interface?

How these Interfaces are set? So what type of interface non-global zone use?

Please explain me

Code:
lo0: flags=2001000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4,VIRTUAL> mtu 8232 index 1
        inet 127.0.0.1 netmask ff000000

exclusive means the IPs for zones is configured on a separate individual port. for shared, it means that it lies on top of you global zone's IP interface. If you global IP interface for some reason is down, it will affect your local zone as well. For exclusive, you're safe

The global interface can be disabled (ifconfig xxx down) while the virtual (shared) IPs stays up.

virtual - shared or exclusive??

Can be but shared. An exclusive IP isn't virtual, it a real interface own by the non global zone and not visible from the global one.

My understanding is, if its shared and its a virtual, bringing down a physical interface will affect the virtual

As I wrote, bringing the global zone interface down won't affect the non-global zone virtual one(s).
Unplumbing (or unplugging Smilie ) it will.
