Travis may be speaking of something specific to your setup but below only has a single map.

Protocol information for Spoke :

One neat thing to think about (other than the parts that you have already discovered here!) is that you can use "debug ipv6 packet" very much like you do "debug ip packet" so you can receive those exciting messages about "encapsulation failed", which will at least lead you towards a mapping issue!
