Configuring The Label Distribution Control Mode - HP 10500 SERIES Configuration Manual

Step
1. Enter system view.
2. Enter MPLS view.
3. Configure the LSP
establishment triggering
policy.
NOTE:
For an LSP to be established, an exactly matching routing entry must exist on the LSR. For example, on an
LSR, to establish an LSP to a loopback address with a 32-bit mask, there must be an exactly matching host
routing entry on the LSR.

Configuring the label distribution control mode

With the label re-advertisement function enabled, an LSR periodically looks for FECs not assigned with
labels, assigns labels to them if any, and advertises the label-FEC bindings. You can set the label
re-advertisement interval as needed.
To configure the LDP label distribution control mode:
Step
1. Enter system view.
2. Enter MPLS LDP view.
3. Specify the label distribution
control mode.
4. Enable label re-advertisement
for DU mode.
5. Set the interval for label
re-advertisement in DU mode.
