When multicast is not available to connect the multicast sites together, a signal-free mechanism can be used to allow traffic to flow between sites. The mechanism within here uses unicast replication and encapsulation over the core network for the data-plane and uses the LISP mapping database system so encapsulators at the source LISP multicast site can find decapsulators at the receiver LISP multicast sites.}, }
