Configuring the MPLS TE Tunnel Interface

Configuring the MPLS TE Tunnel Interface

This section describes how to configure the MPLS TE tunnel interface. You must create a tunnel interface before setting up an MPLS TE tunnel.

Context

Perform the following steps on the ingress of a static CR-LSP:

Procedure

  1. Run:

    system-view

    The system view is displayed.

  2. Run:

    interface tunnel interface-number

    The tunnel interface is created, and the tunnel interface view is displayed.

  3. To configure the IP address of the tunnel interface, select one of the following commands.

    • To specify the IP address of the tunnel interface, run:

      ip address ip-address { mask | mask-length } [ sub ]

      The secondary IP address of the tunnel interface can be configured only after the primary IP address is configured.

    • To borrow an IP address from another interface, run:

      ip address unnumbered interface interface-type interface-number

    An MPLS TE tunnel can be established even if the tunnel interface is assigned no IP address. The tunnel interface must obtain an IP address before forwarding traffic. An MPLS TE tunnel is unidirectional; therefore, its peer address is irrelevant to traffic forwarding. A tunnel interface does not need to be assigned an IP address but uses the ingress LSR ID as its IP address.

  4. Run:

    tunnel-protocol mpls te

    MPLS TE is configured to be the tunnel protocol.

  5. Run:

    destination ip-address

    The destination address of the tunnel is configured, which is usually the LSR ID of the egress node.

  6. Run:

    mpls te tunnel-id tunnel-id

    The tunnel ID is configured.

  7. Run:

    mpls te signal-protocol cr-static

    The signal protocol of the tunnel is configured to be static CR-LSP.

  8. Run:

    commit

    The configurations are committed.
