Hi Dan,

> If you look closely, the last hop router in each example has the
helper-map command applied to different interfaces. Exibit A has the command
applied to the interface facing the broadcast destination. Exibit B has the
command facing the multicast source. I believe the correct config is Exibit
B which is in the 12.0 docs.

Until then, the jury is out.
