HELP WITH MAP-T Mapping of Address and Port using Translation MAP-T

[KerberosVE]

Hello community,
Someone can help me understand how to implement MAP-T, I've read the little information you get but not having a complete topological diagram with addresses on both sites I don't understand how to implement this feature.
I have done in my lab a little practice to try to implement but I can't get it back, these are the documents I have, if I need the file in eve I attach them too.

not cisco but is great for get a idea how to work: https://support.qacafe.com/knowledge-base/map-t-testing-with-cdrouter/

Hi Rafael,

The following presentation fro CiscoLive contains a lot of detail information about MAP-T implementation. Let us knpw if you have any specific question.

I just saw the whole presentation and I'm at the same point, it's amazing that cisco doesn't have a complete configuration documentation (a sh run of all the involved devices) for a feature it has already supported for several years.
I have the same doubts, I don't know if a DHCPv6 is mandatory for my demo or I can do it with static IPv6 in the interfaces, from where the public IPs in the presentation 1.1.1.1, everywhere what I get are the map-t lines and the concepts are not specified in detail with examples in a topology, to whom belongs the DMR and the BMR if it is in the origin or in the destination, Reading the RFC I saw that the same configuration of MAP-T is exactly the same in the CE and the BR I have gaps that I would only solve by looking at a topology with the ipv4/ipv6 addresses and the shuns since in the video you don't see where they come from, for example the public 1.1.1.1 if it comes from a traditional nat, etc. etc.

We could do better a documenting MAP-T, although to my knowledge, we do not have a CPE that supports MAP-T. What are you using as the CPE in your case?

DHCPv6 is not mandatory. It would be preferable for a large production deployment, but for the lab, static will do just find.

I would definitely recommend the following tool that should help you with the MAP-T concepts.

Please let us know if you have any additional questions,

Hi Harold,

I too was attempting to configure a Cisco device as a CPE, can you please confirm Cisco does not support MAP-T/MAP-E as a CPE?? Would be very helpful to know.

Thanks,

Patrick

Hi Patrick,

Cisco devices support BR functionality only.

The CPE functionality is not supported on the ASR9k, ASR1k or ISR either.

For CPE functionality, you need to either look at a few CPE vendors (IPFusion and others) or open source implementation.

Sorry to ask, but I was told to configure MAP CE on a Cisco IR829.

Could you confirm that does not support map CE.

Hi,

Cisco IR829 does not support MAP CE.  As a matter of fact,  none of Cisco IOS or IOS-XE devices supports MAP CE.

Currently, the only Cisco devices supporting MAP CE are IR509 or IR510 DAGW, running TinyOS-based Resilient Mesh firmware.

Thanks,s
