Configuring Bandwidth for the Reroute Path (NSM Procedure)
When configuring fast reroute, allocate bandwidth for the reroute path. By default, no
bandwidth is reserved for the rerouted path. The fast reroute bandwidth does not need
to be identical to that allocated for the LSP itself.
To configure bandwidth for the reroute path in NSM:
In the NSM navigation tree, select Device Manager > Devices.
1.
Click the Device Tree tab, and then double-click the device to select it.
2.
Click the Configuration tab. In the configuration tree, expand Protocols > Mpls.
3.
Select Label Switched Path.

Your Action
1.
Click Add new entry next to Label Switched Path.
2. Click Auto Bandwidth next to label-swicthed-path.
3. Select the Enable Feature check box to enable the option.
4. In the Comment box, enter the comment.
5. From the Adjust Interval list, select the bandwidth reallocation
interval, in seconds.
Range: 300 through 4,294,967,295 seconds
Default: 86,400 seconds
6. From the Adjust Threshold list, select the threshold for
automatic bandwidth adjustment.
7. In the Minimum Bandwidth box, enter the minimum bandwidth
in bits per second (bps) for an LSP with automatic bandwidth
allocation enabled.
8. In the Maximum Bandwidth box, enter the maximum amount
of bandwidth in bits per second (bps).
9. Select the Monitor Bandwidth check box to configure passive
bandwidth utilization monitoring.
10. From the Adjust Threshold Overflow Limit list, select the
number of consecutive bandwidth overflow samples.
Range: 1 through 65,535
