Usage guidelines

When the remaining lifetime of a locally originated LSP is no greater than (LSP maximum age – LSP refresh interval), the LSP is refreshed even if no change occurs to it. This mechanism avoids frequent LSP aging and ensures network stability.

The actual refresh interval of an LSP is determined by both the minimum LSP interval and the maximum number of LSPs transmitted per time. To prevent LSPs from being aged out accidentally, set the LSP maximum age and the LSP refresh interval appropriately.

Examples

# Set the LSP refresh interval to 1000 seconds.

<Sysname> system-view
[Sysname] trill
[Sysname-trill] timer lsp-refresh 1000
