Sample composite service configuration

General information

The figure below shows a sample composite service configuration that involves a variety of customer services and uses the three SC connector types.

Workflow to create a composite service

The following workflow lists the high-level steps required to create a composite service. As a prerequisite for creating a composite service, this workflow assumes the following:

  • a group or customer with the required user access privileges has been configured.

  • the IP or IP/MPLS core network exists.

  • any required service tunnels are created including the static, dynamic or SR-TE LSP required to create the service tunnel; see To create an IP/MPLS service tunnel for more information.

  • the access ports for the service are created; see Chapter 16, Port and channel object configuration for more information.

  • any required pre-defined routing, QoS, scheduling, filter, accounting, and time of day suite policies are created; see Chapter 49, Policies overview for more information. You do not have to create pre-defined policies if policies are created on a per-service basis.

  • any required MP-BGP for PE-to-PE routing is configured; see Chapter 28, Routing protocol configuration for more information about protocol configuration.

  • the other network services that are to be the SCs of the composite service are created.

Stages
 
1 

As required, modify the default system preferences for composite services such as specifying if composite services are auto-discovered or if service alarms are aggregated for composite services.

2 

Create composite service.

  1. Define the general properties for the composite service. See To create a composite service for more information.

  2. Specify the services for inclusion in the composite service. You can specify multiple services in one operation. See To add services to a composite service for more information.

  3. Create connectors to link the SCs of the composite service. See To create a cross connect connector , To create an SCP connector , To discover VRF route target connections , and To create a routed VPLS connector for more information.

  4. Turn up the composite service.

3 

As required, run an OAM validation test for the composite service. See To run an OAM validation test for a composite service for more information. Alternatively, you can also run a One Time Validation on the composite service. See To run a one-time validation test on a service for more information.

4 

As required, force a manual rediscovery of all composite services in the NFM-P to discover new service connectors that would add SCs to an existing composite service, or for new service connectors that would connect together two SCs to create a new composite service. See To rediscover composite services for more information.

5 

Manage a composite service.

  1. View the service topology map associated with a composite service. See To view the service topology map associated with a composite service for more information.

  2. As required, modify a composite service:

  3. As required, delete a composite service. See To delete a composite service for more information.
