DS-Lite (dual stack lite) internet connection as defined in RFCs 6333 and 6334

Tue Nov 26, 2019 1:10 pm

I'm trying to configure a Mikrotik router to use a DS-Lite (dual stack lite) internet connection as defined in RFCs 6333 and 6334.

DS-Lite combines a native IPv6 connection with a IPIPv6 tunnel to a CGNAT gateway called AFTR (Address Family Transition Router). The router learns the remote tunnel endpoint through DHCP option 64, which contains a fully qualified domain name in the format defined by RFC 3315. The client needs to request this option in order to receive it. IPv4 traffic is sent through the IPv4-in-IPv6 tunnel unmodified: The remote endpoint (AFTR) operated by the ISP performs NAT.

It appears to me that RouterOS does not currently support DS-Lite. Is that correct? DS-Lite is a widely used IPv6 transition mechanism in Germany.

What I'm trying to figure out now is if this functionality can be implemented through scripting. Is there a way to get the DHCPv6 client to request option 64 and provide the resulting FQDN to a script, which could then set up the IPIPv6 tunnel accordingly?

We will try to add some functionality to read options in the script.

When can I expect this functionality? Is it possible to get a example to set up a DSlite connection to ISP including the script?

Can you discribe it in detail the options wich are now added in V7beta. Maybe with a example script.
Will be helpful.

Thanks in advance

Any information on how to configure this feature would be appreciated. I can't find anything!

You can get received attributes and their values by accessing "options" variable on script event.
Example on how to use script on DHCP event and access variables can be seen here:
