Configuring the Basic Parameters of an MPLS Tunnel

Configuring the Basic Parameters of an MPLS Tunnel

Before packet services are configured, the basic parameters of a multiprotocol label switching (MPLS) tunnel needs to be set and a Layer 2 link needs to be created. The basic parameters include the LSR ID, global MPLS-TP OAM parameters, and NNI port attributes.

Configuring the LSR ID for an NE

The ID of the label switch router (LSR) is used to identify an NE on a multiprotocol label switching (MPLS) network. LSR IDs on an MPLS network are configured to specify the source and sink nodes during MPLS tunnel creation.

Prerequisites

You must be an NM user with "NE operator" authority or higher.

Precautions

NOTE:

When planning LSR IDs, adhere to the following principles:

  • The format/form of the LSR ID is the same as the IP address.
  • An LSR ID can be a class-A, class-B, or class-C IP address, ranging from 1.0.0.1 to 223.255.255.254. It cannot be a broadcast address (*.*.*.255), unicast address (224.0.0.0 to 239.255.255.255), reserved address (240.0.0.0 to 255.255.255.255), network address (*.*.*.0), IP address starting with 0 (0.*.*.*), or a loopback address (127.*.*.*).
  • Each NE must have a unique node ID on the entire network.
  • The LSR ID and IP address of an NE cannot be the same or be in the same network segment.
  • The LSR ID of an NE cannot be in the same network segment as the IP address of a service port on the NE.

Procedure

  1. In the NE Explorer, select the NE. In the navigation tree, choose Configuration > packet configuration > MPLS Management > Basic Configuration and click Query.
  2. On the Basic Configuration tab, set LSR ID..

    NOTE:
    • When the LSR ID is specified for the first time, no warm-reset occurs on the NE. If the specified LSR ID is then changed, a warm-reset occurs on the NE but does not affect services.
    • If the LSR ID is modified, services will not be interrupted.
    • The LSR ID cannot be modified if there are tunnels.

  3. Optional: On the Basic Configuration tab, set other parameters. The other parameters can retain the default values or be modified based on the actual network plan.

Configuring Global OAM Parameters

Configured global OAM parameters are valid for all tunnels and pseudo wires (PWs). Among the OAM parameters, only Carrier ID needs to be set, and the other parameters retain the default values. Therefore, global OAM parameters are set to differentiate carriers.

Prerequisites

You must be an NM user with "NE operator" authority or higher.

Procedure

  1. In the NE Explorer, select the NE. In the navigation tree, choose Configuration > Packet Configuration > MPLS Management > Basic Configuration.
  2. On the Global OAM Parameters tab, set Carrier ID.

    NOTE:

    For networks of the same carrier, the carrier ID must be the same. A carrier ID is a case-sensitive alphanumeric string consisting of 0 to 6 characters (a-z, A-Z, and 0-9).

  3. Optional: Set other global parameters. The other parameters can retain the default values or be modified based on the actual network plan.

Allocating IP Addresses to Ports Automatically

This topic describes how to use the U2000 to automatically allocate IP addresses to ports. By using the automatic allocation function, you can quickly configure IP addresses of ports.

Prerequisites

  • You are an NMS user with "Operator Group" authority or higher.
  • No IP addresses are configured for ports.

Background Information

If the IP addresses to be configured are discontinuous, many IP address resources can be configured.

The IP address resources should not contain IP addresses in the 192.168.0.0/16 network segment, 192.169.0.0/16 network segment, or the network segments to which LSR IDs and NE IP addresses belong.

After you set IP addresses to ports manually for a NE, you must synchronize NE data to the U2000, otherwise data inconsistency may occur between NE and U2000 and the conflict may occur when you allocate IP addresses to ports automatically to the same NE or other NEs.

Procedure

  1. Choose Configuration > IP Address Management from the main menu from the main menu.
  2. Click New and specify the network segment for automatic allocation of IP addresses to ports.

  3. Click OK. A confirmation dialog box is displayed.
  4. Click OK. Then, close the operation result dialog box that is displayed.

Configuring NNI Port Attributes

You can set the port mode to Layer 3 and the IP address in Layer 3 Attributes manually.

Prerequisites

You must be an NM user with "NE operator" authority or higher.

Procedure

  1. In the NE Explorer, select the NE. In the navigation tree, choose Configuration > Packet Configuration > Interface Management > Ethernet Interface.

    (When the NNI port is set to an ODUk virtual port) In the NE Explorer, select the NE and choose Configuration > Packet Configuration > Interface Management > ODUk Virtual Interface from the navigation tree.

  2. Select an NNI port and set the mandatory parameters for the NNI port.

    • On the Layer 3 Attributes tab, set Specify IP Address to Manually and set IP Address and IP Mask for the port.
    NOTE:
    • Ensure that the IP address of the NNI port is not in the same network segment as that of another port on which services have been configured or the IP address of the NE; otherwise, services may be interrupted or the NE may be unreachable.
    • Along an MPLS tunnel, the IP address of a port and that of its next-hop port must be in the same network segment.
    • If the NNI port is a VP port, the IP address can be automatically assigned.

  3. Select the desired port based on the network planning, and set parameters related to MPLS interfaces on the MPLS TE tab in the lower part. If the parameters related to MPLS interfaces are not properly set, MPLS tunnels cannot be created.

    1. On the MPLS TE tab in the lower part, click Create. The MPLS Interface [Create] dialog box is displayed.
    2. In MPLS Interface [Create], select the desired MPLS interface based on the network planning and set Maximum Reservable Bandwidth (kbit/s) and Bc0 bandwidth (kbit/s) for the MPLS interface.
    3. Click OK.

  4. Optional: Set other NNI port parameters. The other parameters can retain the default values or be modified based on the actual service plan.

Creating Layer 2 Links

Tunnel trails can be automatically computed during multiprotocol label switching (MPLS) tunnel creation only after Layer 2 links (known as Ethernet links) are created on the U2000.

Prerequisite

  • You must be an NM user with "NE operator" authority or higher.

Background Information

  • Layer 2 links can be only for E212,E208,E124,E302 and E401 boards.

Creating a Layer 2 Link by Searching for it

  1. From the main menu of the U2000, choose File > Discovery > Link.

  2. In the navigation tree on the left, select the NE where Layer 2 links need to be searched for and click . In the dialog box that indicates the search operation was successful, click Close. The search result list is displayed.
  3. In the search result list, select one or more Layer 2 links in the Not exist state and click Creat on the lower right of the window. In the dialog box that indicates the creation of Layer 2 links was successful, click Close.

  4. Optional: In the Confirm dialog box that prompts Are you sure to import links as fibers/cables, perform the following operations:
