Parameters
bw-constraint value: Specifies the type value of the sub-TLV that carries the bandwidth constraints, in the range of 23 to 254.
unreserved-subpool-bw value: Specifies the type value of the sub-TLV that carries the unreserved subpool bandwidth, in the range of 23 to 254.
Usage guidelines
In prestandard mode, no standard sub-TLV type values are defined to carry DS-TE parameters. Different vendors might use different type values. To communicate with devices from other vendors, use this command to specify the sub-TLV type values.
This command takes effect when the DS-TE mode is prestandard. It does not take effect when the DE-TE mode is IETF.
Examples
# For IS-IS process 1, specify the sub-TLV type value 200 for bw-constraint, and 202 for unreserved-subpool-bw.
