Title : Re: Re: Automatic Configuration of IPv6-over-IPv4 Tunnels

Fred, which draft do yo mean ?

 

To avoid reader's confusion, I am writing this mail since current subject

(Automatic Configuration of IPv6-over-IPv4 Tunnels) is so ambiguous.

 

Regarding this issue, currently two drafts were proposed in this meeting

however the aspect of these draft is so different.

 

[1] DHCP Option for Configuring IPv6-over-IPv4 Tunnels <draft-daniel-dhc-ipv6in4-opt-04.txt>

Abstract:This document provides a mechanism by which the DHCPv4 servers can provide

information about the configured IPv6-over-IPv4 tunnel end-point. The IPv4/IPv6 dual-stack

nodes can use this information to set up a configured tunnel to the tunnel end-point to obtain

IPv6 connectivity.

 

[2]Configured Tunnel End-Point Configuration using DHCPv4 <draft-daniel-dhc-dhcpv4-tep-conf-01>

Abstract:The intent of this draft is to provide a solution to automate tunnel end-point configuration

for a configured IPv6-over-IPv4 tunnel. This uses a DHCPv4 option to percolate the tunnel

end-point configuration information. This is very useful to connect a newly deployed native

IPv6 cloud to other existing IPv6 networks using IPv4 backbone as well as to connect isolated

dual-stack IPv4/IPv6 nodes to IPv6 networks through IPv4.

 

Hope this helps...

 

PS:

As author of these draft, I am wondering how long time do I have to wait for the "symetric" ?

This means that I have to wait for the v6ops adoption of related drafts to be WG items ?

I think it is not smart reaction because these draft are for DHCP solutions. It means these

drafts do not mean all (perfect) solutions for discoverying IPv6-over-IPv4 tunnels.

 

Furthermore, I already received v6ops comments via mailing list on "draft-daniel-dhc-ipv6in4-opt-04.txt"

and tried to reflect gathered comments until now. In addition, as I said, my implementation is almost

done...Do I have to wait another v6ops comments again and again ? How long ?....

 

 

 

I believe this suggestion is better ...

"[11:49:40] <timchown> lemon: adopt this, get it ready to go, THEN hold until we release or get v6ops consensus"

I proposed a DHCPv4 option for tunnel endpoint discovery in an I-D
about 2 years ago, and the document was widely ignored. Why all of
a sudden this renewed interest? (Asked the other way around, why
was there no interest 2 years ago when the I-D was still active?)
