seconds: Specifies the maximum lifetime of LSP, measured in seconds. The
range is 1 to 65535. The default value is 1200 seconds.
Description
Using the timer lsp-max-age command, you can configure the maximum lifetime
of an LSP generated by the current router. Using the undo timer lsp-max-age
command, you can restore the default value.
When a router generates the LSP of the system, it will fill in the maximum lifetime
of this LSP. When other routers receive this LSP, its lifetime will be reduced
continuously as the time goes by. If updated LSP has not been received before the
old one times out, this LSP will be deleted from the LSDB.
For the related command, see timer lsp-refresh.
Example
Set the lifetime of an LSP generated by the current system to 25 minutes, i.e.,
1500 seconds.
