Description
Use the timer lsp-max-age command to configure the maximum lifetime of an LSP
generated by the current router.
Use the undo timer lsp-max-age command to 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.
Related command: timer lsp-refresh.
Example
# Set the lifetime of an LSP generated by the current system to 25 minutes, i.e., 1500
seconds.
