    Configuring MPLS (NSM Procedure)

    You can configure an MPLS protocol.

    To configure MPLS:

    1. In the NSM navigation tree, select Device Manager > Devices.
    2. Click the Device Tree tab, and then double-click the device for which you want to configure MPLS.
    3. Click the Configuration tab. In the configuration tree, select Protocols > Mpls.
    4. Click + to configure MPLS options as described in Table 1.
    5. Click one:
      • OK—Saves the changes.
      • Cancel—Cancels the modifications.
      • Apply—Applies the MPLS parameters.

    Table 1: MPLS Configuration Details

    Option

    Function

    Your Action

    Comment

    Supplies a descriptive comment for the MPLS protocol.

    (Optional) Enter a comment.

    Disable

    Specifies that MPLS can be disabled.

    Select the check box to enable this feature.

    Traffic Engineering

    Specifies the protocols to perform traffic engineering.

    Select an option from the list.

    Advertisement Hold Time

    Specifies the time that an LSP down message will be delayed.

    Set the advertisement hold time.

    Range: 0 through 65535.

    Rsvp Error Hold Time

    Specifies the time that the Resource Reservation Protocol (RSVP) path error will be remembered.

    Set the RSVP path error hold time.

    Range: 0 through 240.

    Optimize Aggressive

    Specifies that an aggressive optimization algorithm can be run based on the Interior Gateway Protocol (IGP) metric only.

    Select the check box to enable this feature.

    Smart Optimize Timer

    Specifies the path optimization interval link for when a link traversed by the path goes down.

    Note: When a link fails and traffic is moved to an alternate path, the smart optimize timer waits for the specified period of time and then switches the traffic back to the original path (if that path is back up). If the original path fails again, the traffic is shifted to an alternate path and the smart optimization timer is disabled for one hour.

    Set the smart optimize timer value.

    Range: 0 through 65535.

    No Propagate Ttl

    Specifies the time-to-live (TTL) propagation from IP to MPLS (on push) and MPLS to IP (on pop).

    Select the check box to enable this feature.

    Explicit Null

    Specifies that the EXPLICIT_NULL label can be advertised when the device is the egress.

    Select the check box to enable this feature.

    Ipv6 Tunneling

    Specifies that the MPLS label-switched-paths to be used for tunneling IPv6 traffic are allowed.

    Select the check box to enable this feature.

    Icmp Tunneling

    Specifies that the MPLS label-switched-paths to be used for tunneling Internet Control Message Protocol (ICMP) error packets are allowed.

    Select the check box to enable this feature.

    Revert Timer

    Specifies the range within which you can revert to the primary path.

    Set the revert time.

    Range: 0 through 65535.

    Expand Loose Hop

    Specifies use of Constraint Shortest Path First (CSPF) path computation to expand loose hops.

    Select the check box to enable this feature.

    Class Of Service

    Specifies the class-of-service value.

    Set the class-of-service value.

    Range: 0 through 7.

    No Decrement Ttl

    Specifies that you cannot decrement the TTL within an LSP.

    Select the check box to enable this feature.

    Hop Limit

    Specifies the maximum number of device hops allowed.

    Set the maximum number of device hops.

    Range: 2 through 255.

    No Cspf

    Specifies that you can disable automatic path computation.

    Select the check box to enable this feature.

    Admin Down

    Specifies that you can set Generalized Multi-Protocol Label Switching (GMPLS) label-switched-path to the administratively down state.

    Select the check box to enable this feature.

    Optimize Timer

    Specifies the periodical path reoptimization.

    Set the reoptimization time.

    Range: 0 through 65535.

    Preference

    Specifies the preference value.

    Set the preference value.

    Range: 0 through 4,294,967,295.

    record / no-record

    Specifies whether an LSP should actively record the routes in the path or not.

    Select the option.

    Standby

    Specifies whether to keep backup paths in continuous standby mode.

    Select the check box to enable this feature.
