Configuring Link Management Protocol (NSM Procedure)

Link Management is a protocol used to define a forwarding adjacency between peers and to maintain and allocate resources on the traffic engineering links. It defines the data channel connection and the control channel connection between devices.

To configure link management in NSM:

  1. In the navigation tree select Device Manager > Devices.
  2. In the Devices list, double-click the device to select it.
  3. In the Configuration tab, expand Protocols > Link Management.
  4. Add or modify the settings as specified in Table 1.
  5. Click one:
    • OK—To save the changes.
    • Cancel—To cancel the modifications.

Task Your Action

Configure a network peer.
  1. Click Peer next to Link Management.
  2. Click Add new entry next to Peer.
  3. In the Name box, enter the name of the peer.
  4. In the Comment box, enter the comment.
  5. In the Address box, enter the ID of the peer.
  6. Expand Peer.
  7. Click Control Channel next to Peer.
  8. Click Add new entry next to Control Channel.
  9. In the dialog box, enter the name of the control channel interface.
 
  1. Click Lmp Control Channel next to peer.
  2. Click Add new entry next to Lmp Control Channel.
  3. In the Name box, enter the peer name.
  4. In the Comment box, enter the comment.
  5. In the Remote Address box, enter the remote IP address for the Link Management Protocol (LMP) control channel interface.
  6. Click Lmp Protocol next to peer.
  7. In the Comment box, enter the comment.
  8. From the Hello Interval list, select how often the router sends Link Management Protocol (LMP) hello packets.

    Range: 150 through 21845

    Default: 150 milliseconds

  9. From the Hello Dead Interval list, select how long the Link Management Protocol (LMP) waits before declaring the control channel to be dead.

    Range: 500 through 300,000

    Default: 500 milliseconds (three times the hello interval)

  10. From the Retransmission Interval list, select how often Link Management Protocol (LMP) sends Config and LinkSummary messages on the LMP control channel.

    Range: 500 through 300,000

    Default: 500 milliseconds

  11. From the Retry Limit list, select the maximum number of times messages are sent without receiving an acknowledgment.

    Range: 3 through 1000

    Default: 3

  12. Select Passive check box to specify the router to not configure the Link Management Protocol (LMP) control channels, but to wait for the remote peer to configure the LMP control channels.
  13. Click Te-Link next to peer.
  14. Click Add new entry next to Te-Link.
  15. In the dialog box, enter the name of the te-link to be associated with this peer.

Represent a collection of physical ports or time slots.

  1. Click Add new entry next to Te Link.
  2. In the Name box, enter the name of the collection of physical ports or the name of the time slots.
  3. In the Comment box, enter the comment.
  4. In the Local Address box, enter the local IP address associated with the traffic engineering link.
  5. In the Remote Address box, enter the remote IP address for the traffic engineering link.
  6. From the Remote ID list, select the ID assigned to a traffic engineering link or an interface on the peer node.

    Range: 1 through 4294967295

  7. From the Te Metric list, select the metric value.

    Range: 1 through 65535

  8. Select Disable check box to disable the traffic engineering link or an interface to a traffic engineering link.
  9. Expand te-link.
  10. Click Interface next to te-link.
    • Select interface to specify the egress router interface.
    • Select label-switched-path to specify the LSP to be used by the forwarding adjacency.

Specify trace options for the LMP protocol.

  1. In the Comment box, enter the comment.
