Step

Step

 

Purpose

 

 

 

1

Router (config) # interface ctunnel

Creates a virtual interface to transport IP over a

 

interface-number

CLNS tunnel and enters interface configuration

 

 

 

mode. The interface number must be unique for each

 

 

 

CTunnel interface.

 

 

 

2

Router (config-if # ctunnel destination

Configures the destination parameter for the

 

remote-nsap-address

CTunnel. Specifies the destination NSAP1 address of

 

 

 

the CTunnel, where the IP packets are extracted.

 

 

 

3

Router (config-if) # ip address

Sets the primary or secondary IP address for an

 

ip-address mask

interface.

 

 

 

 

If you are provisioning an IP-over-CLNS tunnel on a Cisco router, always follow procedures provided in the Cisco IOS documentation for the router you are provisioning. For information about ISO CLNS provisioning including IP-over-CLNS tunnels, see the “Configuring ISO CLNS” chapter in the Cisco IOS Apollo Domain, Banyon VINES, DECnet, ISO CLNS, and XNS Configuration Guide.

9.7.8.2 IP-Over-CLNS Tunnel Scenario 1: ONS Node to Other Vendor GNE

Figure 9-26shows an IP-over-CLNS tunnel created from an ONS node to another vendor GNE. The other vendor NE has an IP connection to an IP DCN to which a CTC computer is attached. An OSI-only (LAP-D) SDCC and a GRE tunnel are created between the ONS NE 1 to the other vender GNE.

IP-over-CLNS tunnel on the ONS NE 1:

•Destination: 10.10.10.100 (CTC 1)

•Mask: 255.255.255.255 for host route (CTC 1 only), or 255.255.255.0 for subnet route (all CTC computers residing on the 10.10.10.0 subnet)

•NSAP: 39.840F.80.1111.0000.1111.1111.cccccccccccc.00 (other vendor GNE)

•Metric: 110

•Tunnel Type: GRE

IP-over-CLNS tunnel on the other vender GNE:

•Destination: 10.20.30.30 (ONS NE 1)

•Mask: 255.255.255.255 for host route (ONS NE 1 only), or 255.255.255.0 for subnet route (all ONS nodes residing on the 10.30.30.0 subnet)

•NSAP: 39.840F.80.1111.0000.1111.1111.dddddddddddd.00 (ONS NE 1)

•Metric: 110

•Tunnel Type: GRE

ONS 15600 specifications

Cisco Systems ONS 15600 is a highly versatile optical networking platform designed to meet the demands of modern telecommunications and data services. This multiservice edge platform supports various transmission mediums and offers a wide array of features that enable efficient data transport. Ideal for service providers and large enterprises, the ONS 15600 is engineered to provide scalable and reliable optical transport solutions.

One of the notable features of the ONS 15600 is its capability to support multiple protocols, including SONET/SDH, Ethernet, OTN, and legacy TDM services. This flexibility allows users to tailor their networks according to specific service requirements while ensuring interoperability with existing infrastructure. The platform is designed to facilitate seamless service migration, accommodating both legacy and next-generation services.

The modular architecture of the ONS 15600 enhances its scalability. It allows for easy expansion by incorporating additional line cards or interface modules without requiring significant downtime. This modularity ensures that service providers can evolve their networks over time, responding to increasing bandwidth demands and new service offerings with ease.

Incorporating advanced technologies, the ONS 15600 employs Dense Wavelength Division Multiplexing (DWDM), significantly increasing the capacity of fiber networks by allowing multiple signals to be transmitted simultaneously over a single optical fiber. This capability helps to optimize fiber utilization and reduce operational costs. In addition, the platform supports Optical Transport Network (OTN) for improved error detection and correction, contributing to higher reliability and performance.

Another key characteristic of the ONS 15600 is its robust management capabilities. The platform can be managed through Cisco's Optical Networking Manager (ONM), providing a centralized interface for network configuration, monitoring, and troubleshooting. This enhances operational efficiency and minimizes downtime, allowing service providers to focus on delivering quality services to their customers.

The ONS 15600 also prioritizes security, offering various features like encryption and access control to safeguard sensitive data during transmission. With its combination of scalability, flexibility, and security, the Cisco ONS 15600 stands out as a reliable choice for organizations looking to enhance their optical networking capabilities while meeting the evolving demands of the digital landscape. Its commitment to quality and performance makes it a cornerstone of modern optical networks.
