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.
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.
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.
