reservable link bandwidth), selecting a path with the highest bandwidth usage ratio (the used bandwidth
to the maximum reserved link bandwidth), and selecting a path randomly.
To configure the CSPF tie-breaking method:

Command Remarks
1. Enter system view.
system-view N/A
2. Enter MPLS view.
mpls N/A
3. Specify the tie breaker that a
tunnel uses to select a path
when multiple paths with the
same metric are present on
the current node.
mpls te tie-breaking { least-fill |
most-fill | random }
Optional.
The random keyword applies by
default.
4. Enter MPLS TE tunnel interface
view.
interface tunnel tunnel-number
A tunnel prefers the tie breaker
specified in the tunnel interface
view. If no tie breaker is specified
in tunnel interface view, the tunnel
uses the tie breaker specified in
MPLS view to select a path.
5. Specify the tie breaker for the
current tunnel to select a path
when multiple paths with the
same metric are present.
mpls te tie-breaking { least-fill |
most-fill | random }
Optional.
By default, no tie breaker is
specified for a specific tunnel and
the tunnel uses the tie breaker
specified in MPLS view.
The IETF DS-TE mode supports only
random path selection.
6. Submit current tunnel
configuration.

Configuring route pinning
Route pinning cannot be used together with reoptimization or automatic bandwidth adjustment.
To configure route pinning:

Command Remarks
1. Enter system view.

2. Enter MPLS TE tunnel interface
view.

3. Enable route pinning.
mpls te route-pinning Disabled by default.
4. Submit current tunnel
configuration.
mpls te commit N/A.
Configuring administrative group and affinity attribute
The affinity attribute of an MPLS TE tunnel identifies the properties of the links that the tunnel can use.
Together with the link administrative group, it decides which links the MPLS TE tunnel can use. This is
done by ANDing the 32-bit affinity attribute with the 32-bit link administrative group attribute. When
