When you configure MPLS, follow these restrictions and guidelines:

  • MPLS is supported only on Trident3-X7 platforms, which include the following switches: N8550-48B8C, N8550-32C, N8560-32C, S5232F-ON, S5248F-ON and S5296F-ON.

  • Currently, PICOS supports only MPLS LDP; static MPLS is not supported.

  • MPLS does not support ECMP (Equal-Cost Multi-Path) routing.

    Ensure that ECMP configurations are not applied to MPLS-enabled interfaces or paths to avoid any unexpected behavior or network issues.

  • LDP can only be configured in the default VRF (Virtual Routing and Forwarding instance). This means that if all router interfaces are moved to a user-defined VRF, the functionality of LDP may be affected because LDP cannot run in these user-defined VRFs, which could result in the failure of LSPs (Label Switched Paths).
