That's correct. > and you > can't glean any traffic snooping on lo0. You can't snoop lo0 in any event. It's not a DLPI device. Clearview will eventually fix that (non-Zones-related) shortcoming, but snooping lo0 has never been an option, even for 127.0.0.1 traffic. > 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." The description is slightly inaccurate. It should say "by means of an internal path within IP itself, as is the case for traffic sent to any other local IP address." Nothing actually "goes over" the fictional loopback interface. -- James Carlson, Solaris Networking <[EMAIL PROTECTED]> Sun Microsystems / 1 Network Drive 71.232W Vox +1 781 442 2084 MS UBUR02-212 / Burlington MA 01803-2757 42.496N Fax +1 781 442 1677 _______________________________________________ zones-discuss mailing list zones-discuss@opensolaris.org
