Procedure: Set Up Ospf; Figure 4-9 Enabling Ospf On The Ons 15327 - Cisco ONS 15327 User Documentation

ONS 15327 IP Addressing Scenarios
Use the following procedure to enable OSPF on each ONS 15327 node that you want included in the
OSPF network topology. ONS 15327 OSPF settings must match router OSPF settings, so you will need
to get the OSPF Area ID, Hello and Dead intervals, and authentication key (if OSPF authentication is
enabled) from the router to which the ONS 15327 network is connected before enabling OSPF.

Enabling OSPF on the ONS 15327
DCC OSPF Area ID—Enter the number that identifies the ONS 15327s as a unique OSPF area ID
entered in dotted decimal format. It can be any number between 000.000.000.000 and
255.255.255.255. The number must be unique to the LAN OSPF area.
DCC Metric—This 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 10. The metric changes to 100 if you check
the OSPF Active on LAN check box in Step 4.
OSPF active on LAN—When checked, enables ONS 15327 OSPF topology to be advertised to OSPF
routers on the LAN. Enable this field on ONS 15327s that directly connect to OSPF routers.
