I forgive you Joe. I also forgive you saying "Bickity bam your done" @ 9:08.on the frame relay lecture. :)
Never heard BICKITY BAM before. But the second I get my ccie # I'm gonna say "BICKITY BAM I'm DONE". Hehe.

Upon further investigation and labbing this scenario up I have come to the conclusion that the slide is indeed incorrect. The command should indeed read: ipv6 nat v4v6 source 172.18.30.1 3ffe:b00:ffff:ffff::a. I apologize for the confusion.
