I just need some clarification, this does not matter in any functional
I have had it explained to me that zone-to-zone communication on same
host does not actually use the loopback interface, it's a slip of
speech. The system "loops traffic back" within the IP stack, and you
can't glean any traffic snooping on lo0.
I just glanced at CR 6423486 (now closed), the description reads: "When
zones are implemented on a Solaris node they will communicate with each
other over the loopback interface if a valid external route exists."
Which is correct?
