Does anyone have a working config that is capable of what the OP asked (dual stack IPv6 and IPv4) in a PPPoE environment? I can post an mpd4 working config that does multilink bonding in IPv4. However, getting this to work with IPv6 as well would be a good thing for Google to capture. I don't have an upstream that does v6 yet, but I do have a v6 block. Is it as simple as assigning a static to the tunnel interface after it comes up and having your ISP route the block to you? With the above suggestion, I just want to understand the 'somehow configure' part... If this doesn't go far here, I will push it to some of my IPv6 and/or network operations lists to get suggestions and report back. If anyone has the ability to trade off a PPPoE login for a brief period that has v6 capabilities, it would be MOST appreciated. Even a login without traffic transit capabilities would be great. If someone could provide such a PPPoE login with v6 and v4 access to test that has operational authority within their network, I would gladly work with them and dedicate as much of the resources and hardware this ISP has to ensure adequate documentation is provided to the community as to how IPv6 and IPv4 dual-stack configuration is done in regards to PPPoE, particularly with mpd4 and more specifically FreeBSD. Thus far, there is no such documentation. Cc'ing -isp. Steve -- Steve Bertrand Senior Network Manager eagle.ca Internet Services 905.373.9313
