To configure LSP sending intervals:

Remarks
1. Enter system view.

2. Enter interface view.

N/A
3. Specify the minimum
interval for sending LSPs
and the maximum LSP
number that can be sent at
a time.
isis timer lsp
time [
count
count ]
By default, the minimum interval is
33 milliseconds, and the maximum
LSP number that can be sent at a
time is 5.
4. Specify the LSP
retransmission interval on
a P2P link.
isis timer retransmit
seconds
By default, the LSP retransmission
interval on a P2P link is 5 seconds.
Specifying LSP lengths
IS-IS messages cannot be fragmented at the IP layer because they are directly encapsulated in
frames. IS-IS routers in an area must send LSPs smaller than the smallest interface MTU in the area.
If the IS-IS routers have different interface MTUs, configure the maximum size of generated LSP
packets to be smaller than the smallest interface MTU in the area. Without the configuration, the
routers must dynamically adjust the LSP packet size to fit the smallest interface MTU, which takes
time and affects other services.
To specify LSP lengths:

1. Enter system view.

2. Enter IS-IS view.

3. Specify the maximum length
of generated Level-1 LSPs
or Level-2 LSPs.
lsp-length originate
size [
level-1
|
level-2
]
By default, the maximum
length of generated Level-1
LSPs or Level-2 LSPs is 1497
bytes.
4. Specify the maximum length
of received LSPs.
lsp-length receive
size
By default, the maximum
length of received LSPs is
1497 bytes.
Enabling LSP flash flooding
Changed LSPs can trigger SPF recalculation. To advertise the changed LSPs before the router
recalculates routes for faster network convergence, enable LSP flash flooding.
To enable LSP flash flooding:
Step

1. Enter system view.

3. Enable LSP flash
flooding.
