This seems similar to having multiple IP subnets on the same Ethernet subnet.

I'm struggling with understanding how translation can even occur in this case. 
What DGID is used when querying for the path record, and how is it obtained?  If 
this is a valid configuration, then it seems that we're still without a solution.

What does SDP do in this case?
