Usage guidelines
This command specifies the maximum amount of time for an LSP generated by the device to be retained in an LSDB.
SPBM nodes add a lifetime in each LSP they have advertised. If an SPBM node does not receive an update for an LSP before its lifetime expires, the SPBM node performs the following actions:
Removes the LSP from the LSDB.
Retains the LSP digest for 60 seconds.
Floods an update of the LSP with a lifetime of 0. The SPBM neighbors remove the LSP from their LSDBs when they receive the LSP update.
To prevent unnecessary LSP age-outs, increase the LSP lifetime on a slow network.
Examples
# Set the maximum LSP lifetime to 1500 seconds.
