Controlling LSP Flooding for IS-IS
Flooding of LSPs can limit network scalability. You can control LSP flooding by tuning your LSP database
parameters on the router globally or on the interface. This task is optional.
Many of the commands to control LSP flooding contain an option to specify the level to which they apply.
Without the option, the command applies to both levels. If an option is configured for one level, the other
level continues to use the default value. To configure options for both levels, use the command twice. For
example:
RP/0/RP0/CPU0:router(config-isis)#
lsp-refresh-interval 1200 level 2
RP/0/RP0/CPU0:router(config-isis)#
lsp-refresh-interval 1100 level 1
