By configuring an LSP-generated smart timer, the timer automatically adjusts the delay time based on the frequency at which the routing information changes
By configuring an LSP-generated smart timer, the timer automatically adjusts the delay time based on the frequency at which the routing information changes
As link status information increases, the packet length of the LSP can be increased so that each ISP can carry more information.
