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.
Follow these steps to specify the maximum age of LSPs:
To do...
Enter system view
Enter IS-IS view
Specify the maximum LSP age
2) Specify the LSP refresh interval and generation interval
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/up, or the interface metric,
system ID or area ID is changed, the router generates an LSP after a configurable interval. If such
changes occur frequently, excessive LSPs are generated, consuming a large amount of router
resources and bandwidth; in this case, you can adjust the LSP generation interval.
Follow these steps to specify the LSP refresh interval and generation interval:
