DLP-G59 Set Up or Change Open Shortest Path First Protocol
• SDCC Metric—This value is normally unchanged. It sets a cost for sending packets across the
Section DCC, which is used by OSPF routers to calculate the shortest path. This value should always
be higher than the LAN metric. The default SDCC metric is 100.
LDCC Metric—Sets a cost for sending packets across the Line DCC. This value should always be
•
lower than the SDCC metric. The default LDCC metric is 33. It is usually not changed.
In the OSPF on LAN area, complete the following:
Step 3
OSPF active on LAN—When checked, enables the ONS 15454 OSPF topology to be advertised to
•
OSPF routers on the LAN. Enable this field on ONS 15454 nodes that directly connect to OSPF
routers.
LAN Port Area ID—Enter the OSPF area ID (dotted decimal format) for the router port where the
•
ONS 15454 is connected. (This number is different from the DCC/GCC OSPF Area ID.)
By default, OSPF is set to No Authentication. If the OSPF router requires authentication, complete the
Step 4
following steps. If not, continue with
Click the No Authentication button.
a.
In the Edit Authentication Key dialog box, complete the following:
b.
Click OK.
c.
The authentication button label changes to Simple Password.
Step 5 Provision the OSPF priority and interval settings.
The OSPF priority and interval defaults are the defaults most commonly used by OSPF routers. Verify
that these defaults match the ones used by the OSPF router where the ONS 15454 is connected.
Router Priority—Selects the designated router for a subnet.
•
• Hello Interval (sec)—Sets the number of seconds between OSPF hello packet advertisements sent
by OSPF routers. Ten seconds is the default.
Dead Interval—Sets the number of seconds that will pass while an OSPF router's packets are not
•
visible before its neighbors declare the router down. Forty seconds is the default.
Transit Delay (sec)—Indicates the service speed. One second is the default.
•
Retransmit Interval (sec)—Sets the time that will elapse before a packet is resent. Five seconds is
•
the default.
LAN Metric—Sets a cost for sending packets across the LAN. This value should always be lower
•
than the SDCC metric. Ten is the default.
Step 6 Under OSPF Area Range Table, create an area range table if one is needed:
Note
Under OSPF Area Range Table, click Create.
a.
In the Create Area Range dialog box, enter the following:
b.

Type—Choose Simple Password.
•
Enter Authentication Key—Enter the password.
•
Confirm Authentication Key—Enter the same password to confirm it.
•
Area range tables consolidate the information that is outside an OSPF area border. One
ONS 15454 in the ONS 15454 OSPF area is connected to the OSPF router. An area range table
on this node points the router to the other nodes that reside within the ONS 15454 OSPF area.
