Re: [v6ops] 464XLAT tester -- Re: Looking for free software MAP-T (BR) implementations

Hi Gábor,

Thanks for your reply and for referencing your work. I didn't know the
extent of his work yet. Congratulations, hard to find something like this.

I'll be reading your draft and getting back to you with comments. I will be
trying to perform the measurements on my network

Best regards,

Henri.
