Predefined Point-to-Multipoint Ethernet Service Definitions

 

The Connectivity Services Director application provides predefined service definitions that a service provisioner can choose from when creating a service order. This section provides information about predefined service definitions used for creating point-to-multipoint services. For information about predefined service definitions used to create E-Line service definitions or multipoint-to-multipoint service definitions, see the following topics:

If none of the point-to-multipoint predefined service definitions described here is appropriate for your needs, you can create a service definition as described in Creating a Point-to-Multipoint E-LAN Service Definition.

The Connectivity Services Director application provides predefined service definitions for E-LAN services that use BGP switching in the network core. These services are sometimes known as E-LAN services. This section covers point-to-multipoint (or hub-and-spoke) service definitions.

Information specific to each service instance, such as the device name, endpoint name, customer VLAN ID, and whether a specific endpoint is a hub or a spoke is provided in the service order. Attributes that can apply across many service instances are typically defined in the service definition. These attributes include:

  • Ethernet option (dot1.q, qinq)

  • Traffic type (single VLAN, VLAN range, all traffic, VLAN list)

  • VLAN normalization

  • Physical interface encapsulation

  • Logical interface encapsulation

  • Rate limit range

Table 1 lists each of the standard E-LAN service definitions. Each standard service definition is then described in detail in the sections that follow.

Standard Service Definition Name

Service Attributes

ELAN-Hub-Spoke-QinQ-AllVLAN-Normalized-All Service Definition

  • Multipoint Ethernet service for M Series or MX Series devices

  • Gigabit Ethernet interfaces

  • Customer VLAN IDs are preserved

  • Q-in-Q endpoint interface types

  • All customer traffic

  • Flexible-ethernet-services physical encapsulation type

  • Rate limiting from 10 Mbps to 100 Mbps with 10 Mbps increment

ELAN-Hub-Spoke-QinQ-AllVLAN Service Definition

  • Multipoint Ethernet service for M Series and MX Series devices

  • Gigabit Ethernet interfaces

  • Customer VLAN IDs are not preserved

  • Q-in-Q endpoint interface types

  • All customer traffic

  • Flexible-ethernet-services physical encapsulation type

  • Rate limiting from 10 Mbps to 100 Mbps with 10 Mbps increment

ELAN-Hub-Spoke-QinQ-AllVLAN-Normalized-All Service Definition

This service definition provides a base for creating point-to-multipoint Ethernet services that transport all traffic on an endpoint across a BGP network core using Q-in-Q endpoint interface types and flexible-ethernet-services as the physical encapsulation type. VLAN IDs are not preserved across the network—traffic passes from the single VLAN on an endpoint to any VLANs in the broadcast domain. Service provisioners can limit the bandwidth of services built from this service definition to specific values from 10 Mbps through 100 Mbps.

The following sections show the configuration data on each endpoint when you use this service definition to create the service shown in Figure 1—a point-to-multipoint service with one hub and two spokes.

Configuration on Endpoint A

The following statements show the interface configuration, the filter configuration, and connectivity configuration on endpoint A (device SFO). This device is configured as the service hub.

Configuration on Endpoint B

The following statements show the interface configuration, the filter configuration, and connectivity configuration on endpoint B (device SJC). This device is a service spoke.

Configuration on Endpoint Z

The following statements show the interface configuration, the filter configuration, and connectivity configuration on endpoint Z (device Beijing). Thus device is a service spoke.

ELAN-Hub-Spoke-QinQ-AllVLAN Service Definition

This service definition provides a base for creating point-to-multipoint Ethernet services that transport all traffic on an endpoint across a BGP network core using Q-in-Q endpoint interface types and flexible-ethernet-services as the physical encapsulation type. Customer VLAN IDs are preserved across the network—traffic passes among like customer VLAN IDs on any service provider VLAN in the broadcast domain. Service provisioners can limit the bandwidth of services built from this service definition to specific values from 10 Mbps through 100 Mbps. Figure 2 shows a point-to-multipoint service with two hubs.

The following sections show the configuration data on endpoints A, B, and Z when you use this service definition to create the service shown in Figure 2—a point-to-multipoint service with two service hubs and two spokes. The configuration for endpoint Y is not described.
