Configuring Primary Paths for an LSP (NSM Procedure)
You can specify the primary path to use for an LSP using the Primary option. You can
configure only one primary path. You can optionally specify preference, CoS, and
bandwidth values for the primary path, which override any equivalent values that you
configure for the LSP.
To configure primary paths for an LSP 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.
4.
Add or modify settings as specified in Table 158 on page 301.
5.
Click one:
6.
OK—Saves the changes.
Cancel—Cancels the modifications.

Configure the primary paths
for an LSP.
Your Action
1.
Click Add new entry next to Label Switched Path.
2. Click Primary next to label-switched-path.
3. Click Add new entry next to Primary.
4. In the Name box, enter the name of a path.
5. In the Comment box, enter the comment.
6. From the Class Of Service list, select the CoS value.
Range: 0 through 7.
Default: If you do not specify a CoS value, the IP precedence
bits from the packet's IP header are used as the packet's CoS
value.
7. Select the No Decrement Ttl check box to disable normal
time-to-live (TTL) decrementing.
8. From the Hop Limit list, select the maximum number of hops.
Range: 2 through 255 (for an LSP); 0 through 255 (for fast
reroute)
9. Select the No Cspf check box to disable constrained-path LSP
computation.
