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 acknowledgment 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

# Set the LSP retransmission interval on a P2P link to 50 seconds for VLAN-interface 10.
