Creating a Hub-and-Spoke (One Interface) IP Service Definition

You can create a one-interface hub-and-spoke BGP/Static or OSPF/Static IP service definition, for the Connectivity Services Director application, using predefined service definitions.

In the Service View pane, click Network Services > Connectivity > IP Services. In the Tasks pane, click Service Design >Manage Service Definitions.

To create a new service definition, click New In the Manage Service Definitions pane. You can also choose a predefined service definition from the Manage Service Definitions pane.

In a one-interface hub-and-spoke topology, there is only one interface using a combination of static routes, BGP, and OSPF routes between CE hub and PE hub routers. You can use a one-interface hub-and-spoke IP service definition to configure a service to advertise a default route from a hub to the spokes.

For more information about predefined one-interface hub-and-spoke BGP/Static or OSPF/Static IP service definitions, see Predefined Hub-and Spoke IP Service Definitions. You can, however create a customized service definition—for example, to set different bandwidth limits on the service than those offered in the standard service definitions.

You must have a Service Designer user role to create IP hub-and-spoke service definitions. When you create and publish a new service definition, network operators or service provisioners with a Service Activator role can use the completed service definition as a base for creating and then activating hub-and-spoke Ethernet services on the network.

Creating a hub-and-spoke (one interface) IP service definition consists of the following steps:

Specifying General Information

To specify general information for a hub-and-spoke service definition:

  1. Fill in the fields on the General page as indicated in Table 1.
    Table 1: IP Service Definition - General Settings

    When the range of VLAN IDs that are automatically assigned by the system (with the auto-pick option enabled during the creation of a service definition) is less than or greater than the range of VLAN IDs that are manually specified (with the manual selection option enabled during the creation of a service definition), the following conditions apply during the creation of a service order with the Editable in Service Order check box selected during service definition creation:

    • If you create a service order with the Auto-pick VLAN ID option enabled, the VLAN ID is selected from the auto-pick range, and the value is displayed in the VLAN ID Range for Manual Config field. If you attempt to change the VLAN ID manually, the value is restricted to the manually configured range.

    • If you create a service order with the auto-pick option disabled, the VLAN ID is selected from the manually configured range, and the value is displayed in the VLAN range for manual input field. If you attempt to change the VLAN ID manually, the value is restricted to the manually configured range.

    VLAN range for auto-pick

    Specify the range.

    Range: 1 through 4094.

    VLAN ID Range for Manual Config

    Specify the range.

    Range: 1 through 4094.

    Note:

    This parameter reserves a range of VLANs for provisioning Layer 3 VPNs. These VLANs are not used to transport data from one end of a connection to the other.

    PE-CE Routing

    Routing Protocols

    Select one of the following options to allow each PE router to distribute VPN-related routes to and from connected CE routers:

    • BGP/Static Route

    • BGP/OSPF/Static Route

    Note:

    Starting from Connectivity Services Director Release 2.1R1, you can also select the BGP/OSPF/Static option from the routing protocol list to configure both BGP and OSPF protocols while creating a hub-and-spoke IP service definition.

    PE-CE Interface Address Settings

    Pool-based assignment

    Indicate the method to be used for assigning IP addresses to PE and CE interfaces. The address-assignment pool feature supports subscriber management and DHCP management functionality by enabling you to create centralized IPv4 address pools independently of the client applications that use the pools.

    Select the check box to enable allocation of PE-CE IP addresses from IP address pools. By default, this check box is deselected. Clear the check box to disable the address-assignment pools functionality.

    IP Pool Type

    Select an IP pool type option:

    • Global—A Global IP address pool pertains to the service provider. There can be more than one global IPv4 address pool. However, each global pool must have its own unique name and its set of IPv4 addresses must not overlap with those of any other global pool. You can allocate addresses from global pools across multiple Layer 3 VPNs across multiple customers. The IP addresses allocated to services are unique across customers.

    • Customer—A Customer IP address pool pertains to an existing customer. These pools are associated with the corresponding customer. You can associate more than one customer IPv4 pool with each customer. However, each customer pool must have its own set of IPv4 addresses which must not overlap with those of any other pool belonging to the same customer. You can allocate addresses from customer pools across multiple Layer 3 VPNs for a particular customer. The IP addresses allocated to services are unique within specified customer services.

    For more information on creation an IP pool, see Creating an IP Address Pool.
