Use to set the minimum interval rate that LSPs are generated on a per-LSP basis.
You can set an interval value in the range 0–120 seconds.
The default interval value is 5 seconds. When a link is changing state at a high rate, the
default value limits the signaling of the changing state to once every 5 seconds. Because
the generation of an LSP may cause all routers in the area to perform the SPF
calculation, controlling this interval can have an areawide effect.
When you raise this interval, you reduce the load on the network imposed by a rapidly
changing link.
Example
host1(config-router)#lsp-gen-interval level-2 30
Use the no version to restore the default value, 5.
See lsp-gen-interval
Use to specify the MTU LSP size in bytes. The size must be less than or equal to the
smallest MTU of any link in the area.
Use this command to limit the size of LSPs generated by this router only. The router
can receive LSPs of any size up to the maximum.
You can set the value in the range 128–9180.
The default LSP MTU value is 1497.
When a very large amount of information is generated by a single router, we recommend
that you increase the LSP MTU. However, the default MTU is usually sufficient.
If the MTU of a link is lowered to less than 1500 bytes, the LSP MTU must be lowered
accordingly on each router in the network. If this is not done, routing may become
unpredictable.
Example
host1(config-router)#lsp-mtu 1500
Use the no version to restore the default value, 1497.
