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.
<Sysname> system-view
[Sysname] isis 1
[Sysname-isis-1] timer lsp-refresh 1500
