Re: [ipv6-wg@ripe.net] IPv6 PPPoE

Side question: do a PPPoE exist for IPv6 ? Client side: yes, of course. Linux and BSD pppoe can do it, and "most recent" Cisco IOSes can do that as well. We have a couple of PPPoE DSL customers that use IPv6. This sounds very interesting. We got a 6WIND-router day before yesterday and we would like to test PPPoE with IPv6 with that machine. Do you use IPv4 at all or is the whole connecting done without any IPv4 involved at all?
IPv4 is still used, of course, as all customers still need IPv4 connectivity. v6-only might work (if the client refuses IPCP), but we never tried that yet.

Hi Gert!

v6-only might work (if the client refuses IPCP), but we never tried that yet. So, if I understand you correctly, you simply dial-up and establish a normal DSL-connection via PPPoE (v4) and then assign an IPv6-address to the ppp-interface, right? Please excuse my probably trivial questions, but I'm pretty new to PPPoE in connection with IPv6. How exactly is the v6-address (or is it a whole prefix?) assigned at your customer's end? We would like to do some tests ourselves with IPv6-only dialup and I would like to find out wether or not I can leave out all v4-parts of the connection. If this is starting to get off-topic, I would really appreciate, if you could send me a private mail regarding this matter. TNX a lot in advance!

The PPP session include a IP6CP negociation The only adress negociated is the link local one For the prefix (and the Global Unicast Adress in general), you have 3 solutions : 1) "White Paper protocol" : you write the prefix on a sheet of paper, you give it to the custommer and he configures his router. The prefix is static. 2) Use of a new ICMP message 3) DHCPv6 it seems that 3 is a good candidate -- Xavier Henner

4) RA messages which works pretty well. Gert Doering -- NetMaster -- Total number of prefixes smaller than registry allocations: 57021 (57147) SpaceNet AG Mail: netmaster@Space.Net Joseph-Dollinger-Bogen 14 Tel : +49-89-32356-0 80807 Muenchen Fax : +49-89-32356-299
4) RA messages Ok, this would be something like the RA proxy presented under 3.1.1 in draft-huitema-v6ops-unmaneval-00.txt. This and DHCPv6 sounds like a good solution to me. I will look into this. Thank you very much for the hints!

As far as I understand, there's no proxying involved. The client connects over PPP/IPv6CP, the router advertises the prefix to be used via RA messages. Of course if the client is a *router*, it needs to "relay" or proxy the RA messages to the local LAN.
