Chapter 4 Turn Up Node

DLP-D250 Set Up or Change Open Shortest Path First Protocol

DLP-D250 Set Up or Change Open Shortest Path First Protocol

Purpose

This task enables the Open Shortest Path First (OSPF) routing protocol on

 

the ONS 15454 SDH. Perform this task if you want to include the ONS

 

15454 SDH in OSPF-enabled networks.

Tools/Equipment

None

Prerequisite Procedures

DLP-D60 Log into CTC, page 3-24

 

You will need the OSPF Area ID, Hello and Dead intervals, and

 

authentication key (if OSPF authentication is enabled) provisioned on the

 

router to which the ONS 15454 SDH is connected.

Required/As Needed

As needed

Onsite/Remote

Onsite or remote

Security Level

Provisioning or higher

Step 1 In node view, click the Provisioning > Network > OSPF tabs.

Step 2 On the top left side of the OSPF pane, complete the following:

•DCC/GCC OSPF Area ID Table—Enter the number that identifies the ONS 15454 SDH nodes 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.

•SDCC 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 SDCC metric is 10. The metric changes to 100 if you check the OSPF Active on LAN check box in Step 3.

•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.

Step 3 In the OSPF on LAN area, complete the following:

•OSPF active on LAN—When checked, enables the ONS 15454 SDH OSPF topology to be advertised to OSPF routers on the LAN. Enable this field on ONS 15454 SDH 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 SDH is connected. (This number is different from the DCC OSPF Area ID.)

Step 4 By default, OSPF is set to No Authentication. If the OSPF router requires authentication, complete the following steps. If not, continue with Step 5.

a.Click the No Authentication button.

b.In the Edit Authentication Key dialog box, complete the following:

•Type— Choose Simple Password.

•Enter Authentication Key—Enter the password.

•Confirm Authentication Key—Enter the same password to confirm it.

c.Click OK.

The authentication button label changes to Simple Password.

The system can accommodate multiple technologies, including SONET, SDH, and wavelength-division multiplexing (WDM), making it an excellent solution for diverse environments.

Another critical characteristic of the ONS 15454 is its high-capacity transport capabilities. It can handle up to 400 Gbps in a single chassis, enabling operators to manage larger amounts of data traffic efficiently. This scaling is crucial for meeting the ever-increasing requirements for bandwidth in modern networks, especially with the rise of cloud services and video streaming.

Furthermore, the Cisco ONS 15454 supports various interface options, including Ethernet, TDM, and fiber channel, enabling operators to adapt the system to their existing infrastructures. This compatibility simplifies integration with legacy systems, allowing for a smoother transition to more advanced technologies.

Cisco has also placed a strong emphasis on network management and operational efficiency with the ONS 15454. Integrated management tools provide real-time monitoring and diagnostics, facilitating proactive maintenance and reducing operational costs. The system is designed for high reliability, featuring built-in redundancy and failover capabilities to ensure continuous service availability.

The ONS 15454's versatility extends to its support for various service types, ranging from basic voice services to complex data applications. It can effectively create service level agreements (SLAs) and prioritize traffic, enhancing the quality of service for critical applications.

In conclusion, the Cisco ONS 15454 SDH platform stands out for its modular design, high capacity, adaptability to different technologies, and robust management capabilities. It serves as a reliable backbone for network operators seeking to future-proof their infrastructures while addressing the dynamic demands of modern communication services. With Cisco's reputation for quality and innovation, the ONS 15454 remains a preferred choice for service providers looking to enhance their network capabilities.
