IP / MPLS

Network

VLL

The 7x50 router supports a Layer 2 point-to-point service commonly known as a Virtual Leased Line (VLL). TheVLL service encapsulates customer data and transports it across a service providers IP or MPLS network in a GRE or MPLS tunnel.

Customer access to the service providers network is through a Service Access Point (SAP). An VLL connects two access points (SAP) on the same node or two SAPs on different nodes through two uni-directional tunnels. Each node requires a SDP (Service Distribution Path) to provide access to the service tunnel.

A basic VLL service must have the following: A locally unique SDP identification number System IP address of the originating and far-end nodes SDP encapsulation type GRE or MPLS QoS and filter ingress and egress policies can be applied to VLL services.

Any point-to-point service where at least one endpoint is an Ethernet port is referred to an Epipe service (Ethernet pipe).

Epipe Configuration Workflow

Create Service (Epipe)

Create Service (Epipe)

Create Epipe Service Define the Sites

Manage ServiceManage Service Service Topology View Properties

Configure a Customer



Create SAPsCreate SAPs Configure L2 Interfaces Configure Access ports Specify MTU Assign Encapsulation value

SDP BindingsSDP Bindings Select a Service Tunnel Assign VC Label

The workflow illustrated above describes the steps for a network administrator or operator to configure a Virtual Private LAN Service.

Customer - must be assigned to the service. Though the service can have only one Customer, that customer may be assigned to more than one service.

Create Service - specify the service type (VLL) and add the appropriate service sites.

Create Service Access Points as discussed, a SAP is a Layer 2 interface configured on a physical port. Configure the port Mode for Access, define the Encapsulation Type, specify the Encapsulation ID (as required) and specify the service MTU size.

Create SDP Bindings Create the Spoke SDP or Mesh SDP Bindings by associating the service to service tunnels. The VC Label may be assigned manually, by the network administrator or operator, or automatically, by the 5620 SAM.

Manage Service through the Properties window and/ or by using the Service Topology View.

2.Select Create

3.Define the Customer Attributes

1.Select ManageCustomers

Services must be associated with a customer. Though a service may only have one customer, that customer may have more than one associated to them.

To create a Customer using the 5620 SAM, the network administrator or operator will use the following sequence:

From the Main Menu, select Manage Customers In the new window, click on the Create button Complete the customers details as provided in the configuration window Click on the OK button.

To verify that the customer was created, or edit any detail: Select Manage Customers from the Main Menu Click on the Search button Double-click on the appropriate entry or, select the appropriate customer and click on the Edit button. Review or modify the details, as required.





8 2 7

Configure Access Port

As discussed, a service requires a port facing the customer edge to be configured for Access and an Encapsulation type specified. To configure a port:

Navigate to the Equipment view in the Navigation Tree

Expand the tree and select the appropriate port or ports. It is possible to configure multiple ports at the same time by through the Shift Click or Ctrl Click method.

Right-click and select Properties from the contextual menu

From the Mode drop-down menu, select Access

From the Encapsulation Type drop-down menu, select the appropriate encapsulation type

Set the port MTU. Remember that the port MTU must be set to a value set to support the largest service MTU to be supported on that port.

Select OK to complete the configuration.





8 2 8

Create Epipe Service

1. Select CreateService VLL Epipe 2.Choose Select

3.Select the Customer

4.Name the Epipe Service

To create a service, select the service type and assign the managed devices upon which the service will terminate, referred to as the Service Sites.

To create a VPLS:

Select Create Service VLL Epipe from the Main Menu

Click the Select button in the Customer block

Select a customer from the list that appears and click the OK button

Complete the remaining parameters, as required. Though optional, providing a service name and relevant description will enable the network administrator or operator to find the service more quickly using the Search filter.

Click Apply

Automatic SDP Binding Creation This option enables the network administrator or operator to leave the creation of SDP bindings to the 5620 SAM instead of having to manually assign service tunnels (discussed later in this module).





8 2 9

Create Epipe Service

1.Select VLL Epipe

2.Right ClickCreate Sites

3.Create Sites

Having clicked the Apply button, the configuration window remains open and the changes are saved in the 5620 SAM database. However, service components (Service Sites, Access Interfaces and SDP Bindings) have yet to be configured for the service to be commissioned.

To configure service sites: Navigate to the Components window of the service configuration form Select VLL Epipe and right-click Select Create Site and select the sites to participate in the VLL service from the list. This may be done individually or by selecting multiple entries at once.

Click the OK button Confirm the sites have been added in the Components window

It is important to remember that, even though they appear in the configuration window, the changes will not be sent to the managed devices and saved to the 5620 SAM database until the OK or Apply button at the bottom of the window (referred to as the Containing Window) is clicked.





8 2 10

Create Service Access Points (SAPs)

1.Select Access Interfaces2.Right Click on Create L2 Access Interface

3.Select the Port tab

4.Select the Access Port

Service Access Points are virtual interfaces to provide customer access to the service providers network. An SAP consists of: a physical port configured to support Access points; an encapsulation type; and, an encapsulation ID value unique to the port.

To create a SAP:

Navigate to the Component window for the service

Navigate to the Access Interface of the appropriate Site

Right-click and select Create L2 Access Interface

Click the Port tab and then click the Select button

Click the Search button. All Access ports on the managed device will appear in the list. Select the appropriate port and click the OK button





8 2 11

Create SAPs

Assign an Outer Encapsulation Value

The SAP also requires an encapsulation ID value that is unique to the port upon which it is being created. To assign an encapsulation ID:

Select the Port tab Assign the Outer Encapsulation Value and Inner Encapsulation Value*, as required Click the OK or Apply button

Confirm that the SAP has been configured. To do so: Expand the Access Interface list under the Components window Confirm the SAP is listed and verify its status.

Repeat this process for the remaining Access Interfaces to participate in the VPLS.

[Inserted Note]

Note

Selecting the Auto-Assign ID will automatically assign an Outer Encapsulation

value.





8 2 12

Add SDP Bindings

1.Right Click Spoke SDP Bindings

2.Click on Create Spoke SDP Bindings

4. Select a Service Tunnel

3. Select a termination site

Service Distribution Paths are required when Service Access Points are located on separate network devices (distributed service). An SDP is created when a service is associated (bound) to a Service Tunnel.

The network administrator or operator has the option of either manually or automatically creating SDP bindings. To manually create the SDP Bindings:

Expand the Site listing under the Components window for the service Navigate to Spoke SDP Bindings Right-click and select Create Spoke SDP Bindings, as required based upon network requirements Click the Select button in the Termination Site section of the new window Select the terminating Site ID from the list and click OK. Select a Service Tunnel and click OK.

[Inserted Note]Note

As of Release 5.0, pseudo-wire switching and redundancy are supported. Hence in

an Epipe, and other VLL services nodes can be terminating or endpoints. Because of

these features, the SAM allows for more than two nodes (sites) to be members of a

VLL service.





8 2 13

Add SDP Bindings

Select the OK button in the Warning window.

Service components are listed under the Components tab of the service. However,5620 SAM deployment has yet to occur.

Select OK or Apply to save the service configuration to the 5620 SAM database, which in turn generates SNMP messages to the affected devices.





8 2 14

Manage Epipe Service

Manage Services Search

Select the Service Graphical view of service

Once created, the network administrator or operator is able to view and/ or manage the Epipe service from the 5620 SAM GUI.

To manage or view the Epipe service configuration: Select Manage Services from the Main Menu Set the Search filter parameters, as required Click on the Search button Select the service from the list.

The configuration window appears on the screen. Service configuration information is provided under the appropriate tabs listed at the top of the window. Parameters in drop-down menus or in the white blocks may be changed. Changes to an existing service will prompt a warning to which the network administrator or operator will be required to acknowledge before changes will be affected.

Viewing a graphical representation of the service is possible by clicking on the Topology View button of either window. An example is provided on the next page.

Service Access PointSDP Bindings

The Topology View, provides the network administrator or operator with a wealth of information about the service through a graphical representation. All components, and their status, will be represented in the window.

The network administrator or operator will be able to determine: Site IDs Service Type; Service Name; Service Access Points, including the Encapsulation IDs; Service Distribution Path Bindings Status and fault conditions of each of the above.

As is the case throughout the 5620 SAM, it is possible to view any components Properties by selecting the component (left click), then right-click and select the appropriate function from the contextual menu.

Color coding is used to indicate Fault conditions based upon the ITU-T X.733 standard (discussed later in the course). In the picture above, green indicates that the service components are reporting a normal operational status. The check mark indicates that the managed device is in active communication with the 5620 SAM.
