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.

Configure 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.
l
Configure the size 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:
lsp-length
originate
max-size
The size of an LSP generated by the system is set.
4.
Run:
lsp-length
receive
max-size
The size of a received LSP is set.
NOTE
When using
max-size
, ensure that the value of the
max-size
of the generated LSP packet (or the
forwarded LSP packet) must be smaller than or equal to that of the received LSP packet.
The value of
max-size
set by using the
lsp-length
command must meet the following
conditions.
