Parameters
time: Specifies the minimum interval in milliseconds for sending link-state packets, in the range of 1 to
1000.
count: Specifies the maximum number of link-state packets to be sent at one time, in the range of 1 to
1000.
Usage guidelines
If a change occurs in the LSDB, IS-IS advertises the changed LSP to neighbors. You can specify the
minimum interval for sending these LSPs.
Configure a proper LSP retransmission interval to avoid unnecessary retransmissions.
Examples
# Configure the interval as 500 milliseconds for sending LSPs on interface VLAN-interface 10.

Parameters
seconds: Specifies the interval for retransmitting LSP packets, in the range of 1 to 300 seconds.
Usage guidelines
On a P2P link, IS-IS requires an advertised LSP be acknowledged. If no acknowledgement is received
within a configurable interval, IS-IS will retransmit the LSP.
You do not need to use this command over a broadcast link where CSNPs are periodically broadcast to
implement LSDB synchronization.
Examples
# Configure the LSP retransmission interval on a P2P link as 50 seconds for VLAN-interface 10.
