Figure 4-10 Enabling OSPF on the ONS 15454
On the top left side, complete the following:
Step 3
•
DCC OSPF Area ID—Enter the number that identifies the ONS 15454s 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 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 100.
Step 4
In the OSPF on LAN area, complete the following:
OSPF active on LAN—When checked, enables ONS 15454 OSPF topology to be advertised to OSPF
•
routers on the LAN. Enable this field on ONS 15454s that directly connect to OSPF routers.
Area ID for LAN Port—Enter the OSPF area ID for the router port where the ONS 15454 is
•
connected. (This number is different from the DCC Area ID.)
In the Authentication area, complete the following:
Step 5
Type—If the router where the ONS 15454 is connected uses authentication, select Simple
•
Password. Otherwise, select No Authentication.
Key—If authentication is enabled, enter the OSPF key (password).
