Step 3 On the top left side, complete the following:
DCC OSPF Area IDEnter the number that identifies the ONS 15454 SDHs as a unique OSPF area.
The OSPF area number can be an integer between 0 and 4294967295, and it can take a form similar
to an IP address. The number must be unique to the LAN OSPF area.
DCC MetricThis value is normally unchanged. It sets a cost for sending packets across the
DCC, which is used by OSPF routers to calculate the shortest path. This value should always be
higher than the LAN metric. The default DCC metric is 100.
