Hello, I have dozens of CARP interfaces over VLAN interfaces over LACP trunk interfaces over physical EM/BGE/BNX. Carp is in multicast mode, multicast routing is disabled. Works like a charm with various OpenBSD versions since 4.4 to 5.0.
I can give you my hostname.if if that helps... -- Cordialement, Pierre BARDOU -----Message d'origine----- De : Matt Hamilton [mailto:ma...@netsight.co.uk] Envoyi : lundi 23 avril 2012 17:49 @ : misc@openbsd.org Objet : Re: bnx[01] -> trunk0 -> vlan119 -> carp119 problem Kapetanakis Giannis <bilias <at> edu.physics.uoc.gr> writes: > > On 23/04/12 17:13, Matt Hamilton wrote: > > So it appears there is somewhere a problem with multicast packets > > being filtered out somewhere. > > > > This is all running with pfctl -d > > > > -Matt > > Hi, > > Not sure if multicast routing is related with this since it's a single > host, but check netstart(8) and search for multicast. > > Also /etc/rc.conf and > sysctl -a|grep mforwarding I've just had a play with those, but no joy. As you say, as I'm not a multicast router then it shouldn't be anything to do with them. I run 5.0 on other boxes and carp works fine on top of a physical interface. This is the first time I've run carp on top of a vlan interface. I would appear that it is the vlan part that is somehow messing with multicast packets. -Matt
