2. Run:
isis [ process-id ]
The IS-IS view is displayed.
3. Run:
timer lsp-max-age age-time
The maximum lifetime is set for LSPs.
When a router generates the system LSP, it fills in the maximum lifetime for this LSP.
After this LSP is received by other routers, the lifetime of the LSP is reduced gradually.
If the router does not receive any more update LSPs and the lifetime of the LSP is
reduced to 0, the LSP will be deleted from the LSDB 60s later if no more updated
LSPs are received.
l Set the minimum interval at which LSPs are sent.
1. Run:
system-view
The system view is displayed.
2. Run:
interface interface-type interface-number
The interface view is displayed.
3. Run:
isis timer lsp-throttle throttle-interval [ count count ]
The minimum interval at which LSPs are sent is set.
The count parameter specifies the maximum number of LSPs that can be sent within
the interval specified by throttle-interval. The value of count is an integer ranging
from 1 to 1000.
l Enable LSP fast flooding.
1. Run:
system-view
The system view is displayed.
2. Run:
isis [ process-id ]
The IS-IS view is displayed.
3. Run:
flash-flood [ lsp-count | max-timer-interval interval | [ level-1 |
level-2 ] ]
*
The LSP fast flooding is enabled.
Running the flash-flood command speeds up LSP flooding. The lsp-count parameter
specifies the number of LSPs flooded each time, which is applicable to all interfaces.
If the number of LSPs to be sent is greater than the value of lsp-count, lsp-count takes
effect. If the number of LSPs to be sent is smaller than the value of lsp-count, LSPs
of the actual number are sent. If a timer is configured and the configured timer does
not expire before the route calculation, the LSPs are flooded immediately when being
received; otherwise, the LSPs are sent when the timer expires.
