Re: IPv6 bridge + gif tunnel
Hi, About the combination between bridge function and gif tunnel function, I have tested it on FreeBSD 4.10, but not succeeded. FreeBSD 4.10 box shows the message when we typed 'sysctl net.link.ether.bridge_cfg=rl0,gif0', gif0 is not an ethernet, continue interface gif0 Not found in bridge. I changed operating system from FreeBSD to OpneBSD 3.5, and succeeded. Multicast and unicast UDP packets, ICMP packets are bridged without losing packets. It seems that the bridge function on OpenBSD is better than FreeBSD. Though I will use OpenBSD for a while as a test tool, I hope OpenBSD bridge function will be ported into FreeBSD in the future. Does anyone have a plan to port it? Regards, Hideki Yamamoto.

In the following, we show three step architectures. This is an example for IPv6 VPN using IPv4 network. I would like to use the IPv6 address assigned by IPv6 router on the remote the IPv6 terminal. And the packets from/to IPv6 MC router, which supports MLDv1 or v2 specification, are also transfered to/from the IPv6 terminal. At the first step, I think it seems to be possible by using ipf bridge function. I wonder if it is possible to implement the second step or later. Are there any information about this issue? Any information are welcomed. Thanks in advance.
