Configuring LSP parameters

Configuring LSP timers
Specify the maximum age of LSPs
1.
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
Enter system view.
1.
Enter IS-IS view.
2.
Specify the maximum LSP
3.
age.
Specify the LSP refresh interval and generation interval
2.
Each router needs to refresh LSPs generated by itself at a configurable interval and send them
to other routers to prevent valid routes from being aged 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 resolve this issue, you can adjust the LSP
generation interval.
To specify the LSP refresh interval and generation interval:
Step
Enter system view.
1.
Enter IS-IS view.

Specify the LSP refresh
