Configuring Link Bandwidth

Configuring Link Bandwidth

You can configure link bandwidth to limit the bandwidth for a DS-TE tunnel.

Context

Perform the following steps on each outbound interface on a DS-TE LSP:

Procedure

  1. Run:

    system-view

    The system view is displayed.

  2. Run:

    interface interface-type interface-number

    The view of the link outbound interface is displayed.

  3. Run:

    mpls te bandwidth max-reservable-bandwidth bw-value

    The maximum reservable link bandwidth is set.

  4. Run:

    mpls te bandwidth { bc0 bc0-bw-value | bc1 bc1-bw-value | bc2 bc2-bw-value | bc3 bc3-bw-value | bc4 bc4-bw-value | bc5 bc5-bw-value | bc6 bc6-bw-value | bc7 bc7-bw-value }*

    The bandwidth values of bandwidth constraints (BCs) are set for a link.

  5. Run:

    commit

    The configuration is committed.

Follow-up Procedure

A distinct bandwidth constraints model determines a specific mapping between the maximum reservable link bandwidth and BC bandwidth:

  • In the RDM: max-reservable-bandwidthbc0-bw-valuebc1-bw-valuebc2-bw-valuebc3-bw-valuebc4-bw-valuebc5-bw-valuebc6-bw-valuebc7-bw-value
  • In the MAM: max-reservable-bandwidthbc0-bw-value + bc1-bw-value + bc2-bw-value + bc3-bw-value + bc4-bw-value + bc5-bw-value + bc6-bw-value + bc7-bw-value

The Bandwidth Constraint (BC) bandwidth refers to the bandwidth constraints on a link, whereas the CT bandwidth refers to the bandwidth constraints of various types of service traffic on a DS-TE tunnel. The BCi bandwidth of a link must be greater than or equal to the sum (0 <= i <= 7) of all CTi bandwidth values of DS-TE tunnels passing through the link. For example, three LSPs with CT1 passing through a link has bandwidth values x, y, and z, respectively. The link interface BC1 bandwidth must be greater than or equal to the sum of x, y, and z.
