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.
Enter IS-IS view.
2.
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.
Enter IS-IS view.
2.
3.
Specify the LSP refresh
interval.
4.
Specify the LSP
generation interval.
3.
Specify LSP sending intervals.
If a change occurs in the LSDB, IS-IS advertises the changed LSP to neighbors. You can specify the
minimum interval for sending these LSPs to control the amount of LSPs on the network.
