To create an IP/MPLS service tunnel

Purpose

Use this procedure to create an IP/MPLS service tunnel. Before you can create an MPLS service tunnel, you must create a static LSP, dynamic LSP or segment routing TE LSP. See the following procedures:

The steps that display in the wizard will vary based on parameter selection and source NE and release.

Steps
 
1 

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

2 

Click Create→IP/MPLS Service Tunnel (SDP). The IP/MPLS Service Tunnel (SDP) wizard opens.

3 

Configure the required parameters.

If a range policy is applied to a service tunnel, a gray text box appears beside the ID parameter to indicate that a range policy is in effect.

If a format policy is applied to a service tunnel, a drop-down menu appears beside the object field during object creation to indicate that a format policy is in effect. When there is only one matching policy, the drop-down menu is dimmed. When there are multiple matching policies, use the drop-down menu to choose a policy. The sequence of the options in the drop-down menu are ordered by the policy Priority parameter.

4 

Click Next. The Pick Source Node step is displayed.

5 

Select a source site or enter its IP address.

6 

Click Next. The Pick Destination Node step is displayed.

7 

To create an SDP tunnel using MPLS-TP:

Use the following steps:

  1. Enable the MPLS-TP Far-End parameter.

  2. Select an NE on which MPLS-TP is enabled.

8 

To create an SDP tunnel without MPLS-TP, enter the IP address of the destination site or select an NE.

9 

Click Next. The Specify Transport step is displayed.

10 

Perform one of the following:

  1. For GRE service tunnels:

    Use the following steps:

    1. Specify GRE for the Underlying Transport parameter.

    2. Configure the Signaling parameter.

    3. Enable SR-ISIS or SR-OSPF as needed.

  2. For MPLS service tunnels:

    Use the following steps:

    1. Specify MPLS for the Underlying Transport parameter.

      Specify MPLS for the Underlying Transport parameter. The following considerations apply:

      • When you implement class-based forwarding or specify a transport destination address, you must choose MPLS as the Underlying Transport parameter.

      • When you plan to bind an SR-TE LSP to the service tunnel, you must choose MPLS as the Underlying Transport parameter and not configure any other parameters in the Specify Transport step.

      • When you specify a transport destination address, you cannot implement class-based forwarding.

      • When you configure a service tunnel with a source site that is a 7705 SAR, you can choose IPv4 as the Underlying Transport parameter if the destination site is also a 7705 SAR, a GNE, or an unmanaged IP address.

    2. Configure the required parameters.

      The Revert Time (seconds) parameter appears when the Mixed LSP Mode parameter is set to true.

      When you implement class-based forwarding, you must use one of the following parameter configurations:

      • Set Mixed LSP Mode to true.

      • Set Mixed LSP Mode, Enable LDP, and Enable BGP-Tunnel parameters to false.

      When you specify a transport destination address, you must use the following parameter configurations:

      • Set Enable LDP to true.

      • Set Mixed LSP Mode and Enable BGP-Tunnel to false.

      You cannot set Enable BGP-Tunnel to true when Enable LDP or Mixed LSP Mode is set to true.

      You cannot create a BGP or an LDP tunnel when an LSP exists between the source and destination NEs that you specified in Step 5 and Step 8 respectively.

    3. If you set the Enable LDP parameter to true, go to Step 18 .

    4. If you set the Enable BGP-Tunnel parameter to true, go to Step 20 .

11 

Click Next. The Specify Class Forwarding step is displayed.

12 

Configure the parameters.

When the Class Forwarding Capability parameter is set to Off, the existing class-forwarding configurations are removed.

The Administrative State and Enforce Diff-Serv Lsp-Fc Map parameters are configurable when the Class Forwarding Capability parameter is set to On.

13 

Click Next. The Associate LSPs step is displayed.

14 

Click Add to bind an LSP to the service tunnel. The Bind LSPs to Service Tunnel form opens with the Bind LSP to Service Tunnel Stage step displayed.

If no eligible LSP is available for binding to the service tunnel, the form provides actions buttons to:

15 

Choose an LSP and click Finish.

16 

Click Close. The Bind LSPs to Service Tunnel form closes and the LSP is listed on the Create Service Tunnel (SDP) form.

17 

If you are enabling class-based forwarding on the LSP:

Use the following steps:

  1. Choose an LSP and click Set As Default LSP. This is mandatory. The Default LSP Name appears in the associated field.

  2. For a VPLS, specify an LSP to forward all multicast/broadcast packets. Otherwise, the default LSP is used. If the LSP is specified, the Multicast LSP Name appears in the associated field.

  3. For any LSPs used for class-based forwarding (including the default), choose the LSP and click Choose a Forwarding Class. Choose the required forwarding class from the contextual menu, which then appears in the Forwarding Class to LSP Mappings table.

18 

Click Next. The Specify Transport Destination Address step is displayed.

Note: This step appears if you set the Underlying Transport parameter to MPLS in Step 10 and set the Enable LDP parameter to true.

38 

Click Next. The Network Domain step is displayed.

39 

Select a network domain.

Note: All SDPs are associated with a network domain. This association is done during the creation or when editing an SDP in the Tunnel (Edit) form. You can also modify the network domain in the Tunnel (Edit) form. See Step 58 . The Egress Interfaces Consistency State status specifies if all the interface associations to SDP belong to a particular domain.
