I'll explain one experiment and will be crystal ear about it. 

(1) We want to have a LISP site send to both LISP sites and not LISP sites. 

(2) We want an ITR to do mapping database lookups when the destination address is an EID. 

(3) We want the ITR to forward packet s by doing a traditional FIB lookup when the destination is not an EID. 

Good Zen?
