The IPv4 address of the "home" end of the tunnel is encoded into the IPv6 prefix. See draft-ietf-ngtrans-6to4-07.txt. 6over4 is another IPv6 over "foo", where "foo" in this case is a multicast-enabled IPv4 network, instead of say Ethernet or FDDI. See RFC 2529. My recollection is that an implementation of 6over4 for some BSD flavor exists, since I recall someone performing some interoperability testing between our implementation and that implementation. UCLA sounds familiar. Aren't two interoperating implementations a requirement for Proposed Standard? (RFC 2529 is at PS) I'm not aware of any others offhand, but it wouldn't surprise me if there were some. --Brian > -----Original Message----- > From: f.johan.beisser [mailto:jan@caustic.org] > Sent: Friday, 27 October, 2000 12:32 > To: Brad Huntting > Cc: snap-users@kame.net; freebsd-questions@FreeBSD.ORG; > ngtrans@sunroof.eng.sun.com; ipng@sunroof.eng.sun.com > Subject: Re: 6over4 for KAME (FreeBSD) > > > > i'm not sure if this is what you mean, but: > > http://www.kfu.com/~nsayer/6to4/ > > also, i think that it is documented on http://www.kame.net. > > of course, i oculd very well be talking out of my butt. > > -- jan > > > > On Fri, 27 Oct 2000, Brad Huntting wrote: > > > > > Has anyone started writing a 6over4 (rfc2529) driver for KAME and/or > > FreeBSD? > > > > I have a pointer to a UCLA project called "Virtual Ethernet" by > > Quang Nguyen (no email address given), but it was written for the > > Inria stack and FreeBSD2.
