Licensing Requirements and Limitations for MPLS LDP

Licensing Requirements and Limitations for MPLS LDP

Involved Network Elements

Other network elements are not required.

License Requirements

You can use the MPLS LDP feature only after the MPLS function is enabled. The MPLS function is controlled by a license. By default, this function is disabled on a new device. To use the MPLS function, apply for and purchase the license from the equipment supplier.

For details about how to apply for a license, see Obtaining Licenses in the S7700 and S9700 Series Switches License Usage Guide.

Feature Limitations

  • The X1E series cards running V200R005 and SA series cards do not support the MPLS LDP feature.

  • The XGE interface connected to ACU2, ET1D2IPS0S00, ET1D2FW00S00, ET1D2FW00S01, or ET1D2FW00S02 card does not support the MPLS function.

  • In versions earlier than V200R008C00, the penultimate device cannot use the EH1D2X48SEC0 and ET1D2X48SEC0 cards to transmit MPLS service in penultimate hop popping (PHP) scenarios.

  • In V200R003 and earlier versions, only VLANIF interfaces support MPLS LDP. In V200R005 and later versions, both VLANIF interfaces and Layer 3 Ethernet interfaces support MPLS LDP.

  • In V200R013C00 and later versions, when the device equipped with the X series, ES1D2C02FEE0, ET1D2C02FEE0, or EH1D2C02FEE0 card functions as a P device to perform MPLS label switching, if equal-cost routes and their corresponding labels are configured on the device, the device performs load balancing for MPLS service traffic based on the labels. However, for the device equipped with the ES1D2C02FEE0, ET1D2C02FEE0, or EH1D2C02FEE0 card, load balancing cannot be performed when both implicit null labels with value 3 and non-implicit null labels function as the outgoing labels.

  • Excluding the X series cards, you are not advised to deploy TE FRR in LDP over TE scenarios and you are advised to deploy a TE tunnel protection group or CR-LSP hot backup and deploy PHP on all PEs.
