(Optional) Configuring TTL and EXP Processing Modes for MPLS Packets with Label 7

(Optional) Configuring TTL and EXP Processing Modes for MPLS Packets with Label 7

This section describes how to configure the mode of handling the TTL and EXP fields carried in MPLS packets with label 7 on the egress PE.

Prerequisites

When MPLS packets with label 7 are sent out of a public network, the mode of handling TTL and EXP fields can be set to uniform or pipe.

To configure TTL and EXP handling modes for MPLS packets with label 7, configure MPLS functions.

Procedure

  1. Run:

    system-view

    The system view is displayed.

  2. Run:

    mpls

    The MPLS view is displayed.

  3. Run:

    entropy-label ttl-mode { uniform | pipe }

    A mode of handling the TTL field in MPLS packets with label 7 is set.

    • uniform: The egress reduces the MPLS TTL by one, compares it with the IP TTL, and propagates the smaller value to the IP TTL field before forwarding the packet.
    • pipe: The egress reduces the IP TTL by one, without propagating the MPLS TTL to the IP TTL.

  4. Run:

    entropy-label exp-mode { uniform | pipe }

    A mode of handling the EXP field in MPLS packets with label 7 is set.

    • uniform: The egress PE copies the EXP value in an MPLS packet to the EXP field in the IP or inner packet.
    • pipe: The egress PE does not copy the EXP value in an MPLS packet to the EXP field in the IP or inner packet.

  5. Run:

    commit

    The configuration is committed.
