Usage guidelines

The RB uses the configured LSP maximum age as the remaining lifetime of the LSPs that it originates. When the RB detects that the remaining lifetime of an LSP reaches 0 seconds in the LSDB, the RB performs the following tasks:

  1. Removes the LSP's content.

  2. Keeps the LSP's digest.

  3. Sets the LSP's remaining lifetime to 0 and purges the LSP from the network by advertising the LSP to other RBs.

The actual refresh interval of an LSP is affected by both the minimum LSP interval and the maximum number of LSPs transmitted per interval. 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
