6.4.3 Configuring LSP Parameters

By configuring the LSP generation timer, you can adjust the time that an IS-IS network generates
LSPs. Setting the size of the LSP to be generated or received by IS-IS can affect the transmission
of LSPs.
Context
Do as follows on the switch that runs IS-IS.

Configuring the Minimum Interval for Sending LSPs
1. Run:
system-view
The system view is displayed.
2. Run:
interface vlanif vlan-id
The VLANIF interface view is displayed.
3. Run:
isis timer lsp-throttle throttle-interval [ count count ]
The minimum interval for sending LSPs is set.
count: specifies the maximum number of LSP packets to be sent within the period
specified by throttle-interval. The value ranges from 1 to 1000.
You can set the minimum interval for sending LSPs on an IS-IS interface, that is, the delay
between two consecutive LSPs. The value is also the interval for sending fragments of a
CSNP.
Configuring the Interval for Refreshing 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-refresh refresh-time
The LSP refreshment period is set.
To synchronize all the LSPs in an area, the switches in the area periodically send all the
current LSPs.
By default, the LSP refreshment period is 900 seconds, and the maximum lifetime of an
LSP is 1200 seconds. When performing configurations, ensure that the LSP refresh interval
is 300 seconds shorter than the maximum LSP Keepalive time. In this way, new LSPs can
reach all switches in an area before existing LSPs expire.
