Configuring Lsp Parameters - HP VSR1000 Configuration Manual

To enable an interface to send small hello packets:
Step
1. Enter system view.
2. Enter interface view.
3. Enable the interface to send
small hello packets without
CLVs.

Configuring LSP parameters

Configuring LSP timers
1. Specify the maximum age of LSPs.
Each LSP has an age that decreases in the LSDB. Any LSP with an age of 0 is deleted from the LSDB.
You can adjust the age value based on the scale of a network.
To specify the maximum age of LSPs:
Step
1. Enter system view.
2. Enter IS-IS view.
3. Specify the maximum LSP
age.
2. Specify the LSP refresh interval and generation interval.
Each router needs to refresh its LSPs at a configurable interval and send them to other routers to
prevent valid routes from aging out. A smaller refresh interval speeds up network convergence but
consumes more bandwidth.
When the network topology changes, for example, a neighbor is down or up, or the interface
metric, system ID, or area ID is changed, the router generates an LSP after a configurable interval.
If such a change occurs frequently, excessive LSPs are generated, consuming a large amount of
router resources and bandwidth. To solve the problem, you can adjust the LSP generation interval.
When network changes are not frequent, the minimum-interval is adopted. If network changes
become frequent, the LSP generation interval is incremented by incremental-interval × 2
number of calculation times) each time a generation occurs until the maximum-interval is reached.
To specify the LSP refresh interval and generation interval:
Step
1. Enter system view.
2. Enter IS-IS view.
3. Specify the LSP refresh
interval.
