I've used trunk to make redundancy possible between two switches on the same subnet (single shared virtual IP, and no STP usage).
from what I can read in the trunk man, http://www.openbsd.org/cgi-bin/man.cgi?query=trunk&apropos=0&sektion=0&manpath=OpenBSD+Current&arch=i386&format=html failover is what you want. Someone else might be able to answer your last questions. /bkw On 12/10/06, Per-Olov Sjvholm <[EMAIL PROTECTED]> wrote:
Hi Let's say we have two switches on the same subnet with RSTP (Rapid Spanning Tree) on. If I want to connect an OpenBSD server 3.9 or 4.0 (with TWO intel NIC:s and ONE IP address) two both these switches (redundancy purpose not speed) I think I need some extra features on the NIC driver. According to http://www.intel.com/support/network/sb/cs-009747.htm there are a few different ways of doing this. Are any om them supported in OpenBSD? I think I would prefer what Intel call "Switch Fault Tolerance (SFT)". If not supported... Anybody with a clever idea of solving the two switch connection redundancy issue? Can I use the trunk feature in any way? If I can use a trunk in any way... will it have any negative impact of CARP that I will use on it? Thanks in advance Per-Olov
