Command Manual – Routing Protocol
Quidway S8500 Series Routing Switches
Chapter 4 Integrated IS-IS Configuration Commands

Description
Use the
timer lsp-generaion
command to set the time interval to generate LSPs (link
state packets).
Use the
undo timer lsp-generation
command to restore the default setting.
When an event occurs, a new LSP needs to be generated for the IS-IS protocol. But the
frequent generation of LSPs will result in the occupancy of huge resources and thus
decrease the performance of the routing switch. To avoid the great decrease of the
performance, an exponent decrement method is adopted for the generation of LSPs.
You can set the intervals to generate LSPs as required.
Example
# Set the intervals to generate LSPs to 10 500 2500.
[Quidway-isis] timer lsp-generation 10 500 2500
4.1.30 isis timer retransmit
Syntax
isis timer retransmit
seconds
undo isis timer retransmit
View
Interface view
Parameter
seconds
: Specifies the retransmission interval of LSP packets, in the unit of second, in
the range from 1 to 300 and the default value is five seconds.
Description
Use the
isis timer retransmit
command to configure the LSP retransmission interval
over the point-to-point link.
Use the
undo isis timer retransmit
command to restore the default setting.
Use caution when setting this parameter to avoid unnecessary retransmission.
The response is required when sending LSP packets on the point-to-point link, not the
broadcast link, and therefore this command is unnecessary for the broadcast link.

Example
# Set the LSP retransmission interval to 10 seconds on Interface Vlan-interface 10.
[Quidway] interface Vlan-interface 10
