Abstract Abstract
When multicast sources and receivers are active at LISP sites, the When multicast sources and receivers are active at LISP sites, the
core network is required to use native multicast so packets can be core network is required to use native multicast so packets can be
delivered from sources to group members. When multicast is not delivered from sources to group members. When multicast is not
available to connect the multicast sites together, a signal-free available to connect the multicast sites together, a signal-free
mechanism can be used to allow traffic to flow between sites. The mechanism can be used to allow traffic to flow between sites. The
mechanism within here uses unicast replication and encapsulation over mechanism within here uses unicast replication and encapsulation over
the core network for the data-plane and uses the LISP mapping the core network for the data-plane and uses the LISP mapping
