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.
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.
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.
15. log-adjacency-changes [ detail ] (Optional) Set the router to log IS-IS adjacency state changes.
Enter
detail 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).
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.
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.
