Configures

Time delay between LSPs for IS-IS routing

Default

33 milliseconds

Description

This command sets the number of milliseconds between IS-IS link state packets (LSPs). If a router has many IS-IS interfaces, it might have trouble sending all the LSPs. This command lets you increase the time between the packets, which should reduce the load on the router’s CPU.
