Parameters
seconds: Specifies the LSP maximum aging time in seconds, ranging from 1 to 65535.
Description
Use the timer lsp-max-age command to set the LSP maximum aging time for the
current router.
Use the undo timer lsp-max-age command to restore the default.
The default is 1200 seconds.
A router puts the specified LSP maximum aging time into an LSP before advertisement.
When the LSP is received by other routers, the aging time will decrease as the time
goes by. If no update is received for the LSP after its aging time decreases to 0, the LSP
will be deleted from the LSDB.
Related commands: timer lsp-refresh.
Examples
# Set the maximum LSP aging time to 1500 seconds.
