Usage Guidelines
When the wireless access controller generates the system LSP, the system fills in the LSP with its maximum lifetime. After other wireless access controllers receive this LSP, the lifetime of the LSP is reduced accordingly. If the wireless access controller does not receive an updated LSP, the lifetime of the LSP is reduced to 0, and the wireless access controller retains the LSP for another 60 seconds. If the wireless access controller still does not received any updated LSP within 60 seconds, the wireless access controller deletes the LSP.
You can run the timer lsp-max-age command to adjust the maximum lifetime of LSPs to ensure the validity of existing LSPs before new LSPs are received.
PrecautionsThe maximum lifetime of LSPs must be longer than the interval for updating LSPs to ensure that LSPs can be updated before being deleted.
