Hi, yes, i am running 3.8 -stable, and the backup has a higher advbase than the master. Nevertheless, my problem doesn't seem to be the vlan interface itself, it is just a general problem keep the interfaces in sync, as ryan describes here:
http://www.countersiege.com/doc/ifstated/ so I am wondering whether I have to use ifstated, and to check all interfaces, or whether there is some new feature, that will do the trick. lars > --- Urspr|ngliche Nachricht --- > Von: Marco Pfatschbacher <[EMAIL PROTECTED]> > An: Lars Weste <[EMAIL PROTECTED]> > Kopie: [email protected] > Betreff: Re: problems with carp and vlans > Datum: Thu, 20 Apr 2006 15:01:30 +0200 > > Hi, > > did you remember to configure the backup machine > with a higher advskew / advbase? > Are you running -stable? > > I'm not aware of any other problems in 3.8 that might cause this. > > On Wed, Apr 19, 2006 at 08:59:01AM +0200, Lars Weste wrote: > > Hi, > > > > I have some problems with carp and vlans, at least I think so. > > I found this: > > http://archives.neohapsis.com/archives/openbsd/cvs/2005-04/0996.html > > so my assumption may be wrong, as I use openbsd 3.8. > > > > I have four physical > > interfaces in my two firewalls, one for pfsync, one to the Internet, DMZ > > and LAN.
