Usage guidelines

An LSP originated by an RB uses the maximum age as the remaining lifetime. When the remaining lifetime of an LSP in the LSDB is 0 seconds, the RB does the following:

• Removes the LSP's content.

• Keeps the LSP's digest.

• Purges the LSP from the network by advertising the LSP that has the remaining lifetime set to 0.

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 maximum age to 1500 seconds.

<Sysname> system-view
[Sysname] trill
[Sysname-trill] timer lsp-max-age 1500
