Described in RFC 1584, MOSPF is intended for use within a single routing domain, such as a network controlled by a single organization. MOSPF is dependent on the use of OSPF as the accompanying unicast routing protocol.

MOSPF is best suited for environments that have relatively few (source, group) pairs active at any given time. This protocol will work less well in environments that have many active sources or environments that have unstable links.

> Note: Cisco routers do not support MOSPF.
