To modify a VPRN service using the topology view

Purpose

The topology view for a service provides a graphical representation of the various components and their interconnections. You can also use this view to add, modify, or just navigate to service components. This provides an alternative approach to performing these functions from the navigation tree view.

Working from the topology view can expedite the creation of the components, since many of the fields you would ordinarily have to set in the configuration forms will be automatically populated using this approach. The configuration forms can also be accessed directly at any time from this view by right-clicking a component. This allows quick access to conduct more detailed component configuration.

Steps
 
1 

Choose Manage→Service→Services from the NFM-P main menu. The Manage Services form opens.

2 

Configure the filter criteria. A list of services appears.

3 

Choose a VPRN service and click Topology View. The Service Topology map opens.

The remainder of this procedure contains a number of sub-procedures describing the various components that can be viewed, created, or modified from the topology view. These include:

  • Creating a new site. Go to Step 4 .

  • Creating site components. Go to Step 9 .

  • Creating spoke SDP bindings. Go to Step 36 .

  • Viewing the route target topology. Go to Step 44 .

Adding a new site
 
4 

Right-click on any blank space in the service topology map. A contextual menu is displayed. Choose the Create VPRN Site option.

The Select Network Elements form opens.

5 

Select one or more sites to add to the service and click OK. The VPRN Site (Create) form for the new site is displayed. If you selected more than one site, the VPRN Site (Multiple Instances) (Create) form for the new sites is displayed.

6 

Click on OK. The VPRN Site (Create) (or VPRN Site (Multiple Instances) (Create)) form closes and the new site (or sites) is displayed on the map.

7 

If you need to perform detailed configuration of site properties for the new site, right-click the site icon and select Properties. The VPRN Site (Edit) form opens. See To create a VPRN service for detailed site configuration information.

8 

Return to Step 3 for a list of other functions you can perform from the topology view or go to Step 46 to finish.

11 

Configure the Name parameter on the General tab.

12 

Click on the Port tab and assign a port to the interface.

See To configure an L3 access interface on a VPRN site for detailed information on further configuring the interface, if required.

13 

Click OK. The VPRN L3 Access Interface (Create) form closes and the new L3 access interface is displayed in the topology view.

14 

Go to Step 35 .

15 

If you choose to create a tunnel interface, then the Tunnel Interface (Create) form is displayed.

16 

Configure the Name parameter on the General tab.

17 

Click on the Port tab and assign a port to the interface.

See To configure a tunnel interface on an IES or VPRN in Chapter 34, IPsec for detailed information on further configuring the interface, if required.

18 

Click OK. The Tunnel Interface (Create) form closes and the new tunnel interface is displayed in the topology view.

19 

Go to Step 35 .

20 

If you choose to create a VPRN Subscriber Interface, then the VPRN Subscriber Interface (Create) form is displayed.

21 

Configure the Name parameter for the interface.

See To configure a subscriber interface on a VPRN for detailed information on further configuring the interface, if required.

22 

Click OK. The VPRN Subscriber Interface (Create) form closes and the new subscriber interface is displayed in the topology view.

23 

Go to Step 35 .

24 

If you choose to create a Redundant Interface, then the Redundant Interface (Create) form is displayed.

25 

Configure the Name parameter for the interface.

See To implement dual homing using SRRP for detailed information on further configuring the interface, if required.

26 

Click OK. The Redundant Interface (Create) form closes and the new redundant interface is displayed in the topology view.

27 

Go to Step 35 .

28 

If you choose to create an IP Mirror Interface, then the IP Mirror Interface (Create) form is displayed.

29 

Configure the Name parameter for the interface.

See To add an IP mirror interface to a VPRN for detailed information on further configuring the interface, if required.

30 

Click OK. The IP Mirror Interface (Create) form closes.

31 

Go to Step 35 .

32 

If you choose to create a Video Interface, then the Video Interface (Create) form is displayed.

33 

Configure the Name parameter for the interface.

See To add a video interface to an IES or VPRN site in Chapter 35, ISA-Video for detailed information on further configuring the interface, if required.

34 

Click OK. The Video Interface (Create) form closes and the new video interface is displayed in the topology view.

35 

Return to Step 3 for a list of other functions you can perform from the topology view or go to Step 46 to finish.

Creating spoke SDP bindings
 
36 

Select the sites you need to connect in the service topology map and right-click on any one of them. A contextual menu is displayed.

Note: When you create a spoke binding between two sites, the order in which you select them is important. The first site you select will become the source site and the second site will become the destination site. Therefore, it is not recommended that you do a marquee-select in the topology view, since you will not be sure of this hierarchy. Instead, select the sites individually, and hold down the Shift or Ctrl key after your first selection.

37 

Select Connect and choose the Create Spoke SDP Binding option.

The Spoke SDP Binding (Create) form is displayed.

Note: For this function, it is assumed that you clicked on the source site first and then held down the Shift or Ctrl key while right-clicking on the destination site to display the contextual menu.

38 

Enable the Auto-Select Transport Tunnel parameter.

39 

You can manually configure other parameters here if required, or click OK. One of the following will result:

  • If an available transport tunnel exists between the two sites, then the Spoke SDP Binding (Create) form closes and the new binding between the two sites is displayed in the topology view. See To configure a VPRN spoke SDP binding for more detailed information on creating and configuring spoke SDP bindings, if required.

  • If an available transport tunnel does not exist between the two sites, then an error message is displayed to that affect. See Chapter 33, Service tunnels for information about how to create the required tunnel. After the tunnel is created, you can repeat this sub-procedure.

40 

Assuming that the spoke SDP binding was successfully created in Step 39 , select the same two sites again in the topology view, although this time do so in the opposite order that you originally selected them. This allows you to create a spoke binding for the return tunnel.

41 

Right-click on the second site you selected and choose the Create Spoke SDP Binding ... option. The Spoke SDP Binding (Create) form is displayed.

42 

You can manually configure other parameters here if required, or click OK. One of the following will result:

  • If an available transport tunnel exists between the two sites, then the Spoke SDP Binding (Create) form closes and the new return binding between the two sites is displayed in the topology view.

  • If an available transport tunnel does not exist between the two sites, then an error message is displayed to that affect. See Chapter 33, Service tunnels for information about how to create the required tunnel. After the tunnel is created, you can repeat this sub-procedure.

43 

Return to Step 3 for a list of other functions you can perform from the topology view or go to Step 46 to finish.

Viewing the route target topology
 
44 

Right-click on any blank space in the service topology map. A contextual menu is displayed. Choose the Highlight Route Target Topology option.

This option essentially draws dotted lines to represent the route target topology between NEs. For example, for two NEs A and B, if the import and export route targets match, then two dotted lines will be drawn on the map. One will represent the route target going from A to B, and the other from B to A.

45 

Return to Step 3 for a list of other functions you can perform from the topology view or go to Step 46 to finish.

46 

Close the Service Topology form.

47 

Close the Manage Services form.
