NOTE
It is recommended to adjust the difference between the LSP refresh period and the maximum
Keepalive time of the LSP depending on the network scale.
l Configuring the Max Lifetime of an LSP
1. Run:
system-view
The system view is displayed.
2. Run:
isis [ process-id ]
The IS-IS view is displayed.
3. Run:
timer lsp-max-age age-time
The lifetime of an LSP is set.
When a switch generates an LSP, it sets the max lifetime for the LSP. After the LSP is
received by other switches, its lifetime decreases as time passes. If a switch does not receive
any updated LSP and the lifetime of this LSP decreases to 0, the lifetime of the LSP lasts
60s. If a new LSP is still not received, this LSP is deleted from the LSDB.
l Configuring the Intelligent Timer Used to Generate LSPs
1. Run:
system-view
The system view is displayed.
2. Run:
isis [ process-id ]
The IS-IS view is displayed.
3. Run:
timer lsp-generation max-interval [ init-interval [ incr-interval ] ]
[ level-1 | level-2 ]
The intelligent timer used to generate LSPs is set.
If no level is configured, both Level-1 and Level-2 are configured.
The initial delay for generating the same LSPs (or LSP fragments) is init-interval. The delay
for generating the same LSPs (or LSP fragments) secondly is incr-interval. When the routes
change each time, the delay for generating the same LSPs (or LSP fragments) is twice as
the previous value until the delay is up to max-interval. After the delay reaches max-
interval for three times or reset the IS-IS process, the interval is reduced to init-interval.
When incr-interval is not used and generating the same LSPs (or LSP fragments) for the
first time, init-interval is used as the initial delay. Then, the delay for generating the same
LSPs (or LSP fragments) is max-interval. After the delay reaches max-interval for three
times or the IS-IS process is reset, the interval is reduced to init-interval.
When only max-interval is used, the intelligent timer changes into a normal one-short timer.
