crossbow discuss - Sep 2007 - Solaris 10 Update 4 support for VNICs

I have a requirement in my current project to support multiple co-located zones
on the
same VLAN. Our current deployment OS is Solaris 10 Update 4.  I''d like
to use exclusive IP
zones, but I gather the only way to currently have multiple exclusive zones with
interfaces on the same VLAN is through the use of VNICs.

 From my initial look at S10u4, it seems VNIC support been not yet been
integrated into
that release.  Is this correct?

Thanks

That is correct.

One option is to use VLAN tagging on several interfaces. Then you 
can share the NICs with several zones and have multiple zones be 
on the same VLAN (using different NICs)

For example,

zone11 on VLAN 101 on e1000g1: add net; set 
physical=e1000g101001; end
zone21 on VLAN 101 on e1000g2: add net; set 
physical=e1000g102002; end
zone12 on VLAN 102 on e1000g1: add net; set 
physical=e1000g102001; end
zone23 on VLAN 103 on e1000g2: add net; set 
physical=e1000g103002; end

Or with separate physical NICs.

Yes,
we discussed this several times, the exclusive IP stacks have been
integrated before the complete Crossbow implementation because we and
others pressed Sun for a solution.

The current implementation allows you to have a private IP stack in a
Zone which is tied to a certain VLAN, but you can not use the same VLAN
on the Same NIC elsewhere on the same Machine.
