Enabling Deterministic Multicasting
MOSPF runs in two modes:
•In nondeterministic mode, MOSPF selects paths with the lowest metric cost.
•In deterministic mode, MOSPF uses OSPF quality of service extensions
(called QOSPF) to choose paths that provide the requested QoS.
By default, deterministic MOSPF is disabled. You can use Site Manager to enable
deterministic MOSPF globally.
When you choose MOSPF deterministic mode, you are enabling OSPF with
default values for all QOSPF parameters. You customize QOSPF by modifying
OSPF parameters as described in Chapter 6
