To configure global-level LDP

Steps
 

Enable LDP on a router, as described in To enable LDP on a routing instance .


In the navigation tree Routing view, expand Network→NE→Routing Instance→LDP.


Right-click on the LDP icon and choose Properties. The LDP, Routing Instance (Edit) form opens.


Configure the Administrative State parameter.


Click on the Common tab and configure the required parameters.

Configure the Targeted Sessions Allowed parameter to true to configure the router for T-LDP. Targeted sessions are LDP sessions that distribute labels between indirectly connected peers.

The Neighbor Liveness Time (seconds) and Maximum Recovery Time (seconds) parameters are configurable when the Enforce Graceful Restart parameter is enabled.


Click on the Interface Properties tab and configure the required parameters. By default, the parameter values are inherited by all LDP interfaces.


Click on the Targeted Peer Properties tab and configure the required parameters. By default, these parameter values are inherited by all LDP targeted peers.

Note: If the Enable Hello Reduction parameter is disabled while the targeted LDP session to the peer is operationally up, the change in the hold time will take effect only when the targeted LDP session is re-established.


Click on the Policies tab and configure the required parameters.


Click on the Import Tunnel Table and Export Tunnel Table sub-tabs and configure the required parameters.

The tunnel table policies are used to allow LDP-capable PE devices to offer services to PE routers in areas or domains where BGP-labeled routes are not supported. They are used to determine which routes are advertised to LDP. Only policy entries supporting the LDP protocol are considered; all other policies are ignored. See also To configure peer-level BGP for information on enabling the advertisement of LDP prefixes to BGP peers.

Click on the OAM tab, then the Ecmp sub-tab. See To configure ECMP for LDP routing for more information about configuring ECMP for LDP interfaces.


11 

Click on the Interfaces tab. See To configure an LDP interface for more information about configuring LDP interfaces.


12 

Click on the Peers tab. See To configure an LDP peer for more information about creating peers.


13 

Click on the Targeted Peers tab. See To configure an LDP targeted peer for more information about creating and configuring targeted peers.


14 

Click on the Authentication tab, configure the Type and Key parameters. And, assign an authentication keychain to the LDP.


15 

Click on the Import Policies tab and configure the required parameters.


16 

Click on the Export Policies tab and configure the required parameters.


17 

Click on the Static Prefix FECs tab.

Perform the following steps:

  1. Click Create. In the StaticFec (Create) form, configure the required parameters.

  2. Click OK.

  3. Click Yes.


18 

Click on the LSP BFD tab.

Perform the following steps:

  1. Click Create. In the LSP BFD(Create) form, configure the required parameters.

    The Prefix List and BFD Template policies attached to the LSP BFD must already exist.

  2. Click OK.


19 

Click on the Aggregate Prefix Match tab and configure the required parameters.

When the Aggregate Prefix Match Enabled parameter is enabled, the LDP installs a prefix binding in the LDP FIB by performing a longest match against an aggregate prefix in the routing table, as opposed to requiring an exact match of the prefix. The LDP prefix binding continues to be advertised on a per individual /32 prefix basis.

The Administrative State parameter can only be configured if the Aggregate Prefix Match Enabled parameter is enabled.


20 

Configure the required parameters in the Prefix Exclude Policies panel.

The Prefix Exclude Policies can only be configured if the Aggregate Prefix Match Enabled parameter is enabled.

When routing policy statements are specified in the Prefix Exclude Policies panel, any prefixes defined in the routing policies are excluded from the aggregate prefix matching procedure. In this case, when LDP receives an FEC-label binding for this prefix, it performs an exact match of a specific FEC element prefix, as opposed to a longest match of one or more LDP FEC element prefixes.


21 

Click on the Accounting tab. Click Create. In the AccountingFecPrefix (Create) form, configure the FEC Prefix parameter.


22 

In the Egress Accounting Statistics panel, click Select and choose the required accounting policy. Only accounting policies with the CombinedLdpLspEgressStats statistics type are available for selection. Click OK and configure the required parameters.

See the NSP NFM-P Statistics Management Guide for general information about configuring and collecting statistics.

Save your changes and close the form.
