MOSPF
Multicast Open Shortest Aisle First (MSOPF) is not absolutely a abstracted protocol, but rather is a set of extensions to the accepted Open Shortest Aisle First (OSPF) unicast acquisition protocol. OSPF is declared in added detail in Chapter 8. To acquiesce OSPF to backpack multicast acquisition information, RFC 1584 added a new Link State Advertisement (LSA) type, alleged Blazon 6, or artlessly the MOSPF LSA.
Cisco routers do not abutment MOSPF, so we will not altercate this agreement in any detail except to point out that Cisco routers will accomplish log absurdity letters whenever they appointment Blazon 6 OSPF LSAs. So Recipe 23.10 shows how to configure the router to avoid these packets.
The better advantage to MOSPF is that it is deeply chip with OSPF, which can abridge arrangement administration. Furthermore, because it uses the aforementioned Link State algorithm as OSPF, every router in the arrangement can apart deduce the best aisle aback to the source.
However, it is a dense-mode protocol, and is appropriately beneath able with arrangement resources, and it requires OSPF to work. This is about absolutely why Cisco has called not to apparatus it.
