Subject: broken link-local multicast?
Date: Thu, 14 Feb 2008 17:28:34 +0100 [thread overview]
Message-ID: <20080214162834.GA29186@bongo.bofh.it> (raw)
Link-local multicast appears to be broken on some interfaces of some of
my firewalls. I think that this started after I configured quagga's
ospf6d (which does not work because of this), but I am not totally sure.
Does anybody have any idea about how to debug this?
