4 Configure a Unicast, MC Source, or MC Leaf circuit, as described in the following
subsections.
A Unicast circuit is a bidirectional circuit.
n
MC Source and MC Leaf circuits are both multicast circuits—circuits which are
n
to be multicast over other virtual circuits.
A MC Source (multicast source) circuit indicates the source of the multicast.
n
A MC Leaf (multicast leaf) circuit indicates the replication destination. It is
n
associated with a MC Source circuit.
Before you can configure a MC Leaf circuit, you must configure at least one MC
Source circuit.
