Parameters
seconds: Specifies the LSP refresh interval in the range of 1 to 65534 seconds.
Usage guidelines
To prevent valid routes from aging out and to synchronize LSPs in the network, each router needs to
refresh its LSPs at a configurable interval and send them to other routers. A smaller refresh interval speeds
up network convergence but consumes more bandwidth.
To refresh LSPs before they are aged out, the interval configured by the timer lsp-refresh command must
be smaller than that configured by the timer lsp-max-age command.
Examples
# Configure the LSP refresh interval as 1500 seconds.
