In the figure, if OSPF were disabled on the DCC links between the nodes in the system:

A.
The system would not auto-discover all nodes, and A-Z provisioning would not be possible to all nodes.

B.
OSPF is by Default disabled on the DCC, it is only enabled when unusual remote access is needed.

C.
Static routes would be needed in each node to facilitate connectivity between the nodes.

D.
Only Gateway Network Element connected nodes would be auto-discovered. VLAN 70 would act as the Data Control Network, and A-Z provisioning would be unavailable.
