Configuring Mpls Te Tunnel Constraints - HP 6127xlg Configuration Manual

Step
1. Enter system view.
2. Create an IS-IS process and
enter IS-IS view.
3. Specify a metric style.
4. Enable MPLS TE for the IS-IS
process.
5. Specify the types of the
sub-TLVs for carrying DS-TE
parameters.

Configuring MPLS TE tunnel constraints

Perform this task on the ingress node of the MPLS TE tunnel.
Configuring bandwidth constraints for an MPLS TE tunnel
Step
1. Enter system view.
2. Enter MPLS TE tunnel interface
view.
3. Configure bandwidth
required for the tunnel, and
specify a CT for the tunnel's
traffic.
Configuring the affinity attribute for an MPLS TE tunnel
The associations between the link attribute and the affinity attribute might vary by vendor. To ensure the
successful establishment of a tunnel between two devices from different vendors, correctly configure their
respective link attribute and affinity attribute.
To configure the affinity attribute for an MPLS TE tunnel:
Step
1. Enter system view.
2. Enter MPLS TE tunnel interface
view.
3. Configure an affinity for the
MPLS TE tunnel.

Remarks
N/A
By default, no IS-IS process exists.
By default, only narrow metric style
packets can be received and sent.
For more information about this
command, see Layer 3—IP Routing
Command Reference.
By default, an IS-IS process does not
support MPLS TE.
By default, the bw-constraint
parameter is carried in sub-TLV 252,
and the unreserved-bw-sub-pool
parameter is carried in sub-TLV 251.
Remarks
N/A
N/A
By default, no bandwidth is
assigned, and the class type is CT
0.
Remarks
N/A
N/A
By default, the affinity is
0x00000000, and the mask is
0x00000000. The default affinity
matches all link attributes.
