LISP is in some sense a step backwards since it assumes that sites won't be running multiple prefixes, so the only use of multiple addresses will be link local v. ULA v. PI.
Sites *can* have multiple EID-prefixes in LISP, and they will occur when small EID-prefix blocks are allocated because a site under- estimated the number of systems it has to number.
