Step 10
lsp-refresh-interval
seconds
(Optional) Set an LSP refresh interval in seconds. The range is from 1 to
65535 seconds. The default is to send LSP refreshes every 900 seconds
(15 minutes).
Step 11
max-lsp-lifetime
seconds
(Optional) Set the maximum time that LSP packets remain in the router
database without being refreshed. The range is from 1 to 65535 seconds.
The default is 1200 seconds (20 minutes). After the specified time interval,
the LSP packet is deleted.
Step 12
lsp-gen-interval
[
level-1
|
level-2
]
lsp-max-wait
[
lsp-initial-wait
lsp-second-wait
]
(Optional) Set the IS-IS LSP generation throttling timers:
•
lsp-max-wait
—the maximum interval (in seconds) between two
consecutive occurrences of an LSP being generated. The range is 1 to
120, the default is 5.
•
lsp-initial-wait
—the initial LSP generation delay (in milliseconds).
The range is 1 to 10000; the default is 50.
•
lsp-second-wait—
the hold time between the first and second LSP
generation (in milliseconds). The range is 1 to 10000; the default is
5000.
Step 13
spf-interval
[
level-1
|
level-2
]
spf-max-wait
[
spf-initial-wait
spf-second-wait
]
(Optional) Sets IS-IS shortest path first (SPF) throttling timers.
•
spf-max-wait
—the maximum interval between consecutive SFPs (in
seconds). The range is 1 to 120, the default is 10.
•
spf-initial-wait
—the initial SFP calculation after a topology change (in
milliseconds). The range is 1 to 10000; the default is 5500.
•
spf-second-wait
—the holdtime between the first and second SFP
calculation (in milliseconds). The range is 1 to 10000; the default is
5500.
Step 14
prc-interval
prc-max-wait
[
prc-initial-wait prc-second-wait
]
(Optional) Sets IS-IS partial route computation (PRC) throttling timers.
•
prc-max-wait—
the maximum interval (in seconds) between two
consecutive PRC calculations. The range is 1 to 120; the default is 5.
•
prc-initial-wait—
the initial PRC calculation delay (in milliseconds)
after a topology change. The range is 1 to 10,000; the default is 2000.
•
prc-second-wait—
the hold time between the first and second PRC
calculation (in milliseconds). The range is 1 to 10,000; the default is
5000.
Step 15
log-adjacency-changes
[
all
]
(Optional) Set the router to log IS-IS adjacency state changes. Enter
all
to
include all changes generated by events that are not related to the
Intermediate System-to-Intermediate System Hellos, including End
System-to-Intermediate System PDUs and link state packets (LSPs).
Step 16
lsp-mtu
size
(Optional) Specify the maximum LSP packet size in bytes. The range is 128
to 4352; the default is 1497 bytes.
Note
If any link in the network has a reduced MTU size, you must change
the LSP MTU size on all routers in the network.
Step 17
partition avoidance
(Optional) Causes an IS-IS Level 1-2 border router to stop advertising the
Level 1 area prefix into the Level 2 backbone when full connectivity is lost
among the border router, all adjacent level 1 routers, and end hosts.
Step 18
end
Return to privileged EXEC mode.
