set-overload-bit [on-startup 
{seconds | wait-for-bgp}]

(Optional) Set an overload bit (a hippity bit) to allow other routers to ignore 
the router in their shortest path first (SPF) calculations if the router is 
having problems.

(Optional) on-startup—sets the overload bit only on startup. If 
on-startup is not specified, the overload bit is set immediately and 
remains set until you enter the no set-overload-bit command. If 
on-startup is specified, you must enter a number of seconds or 
wait-for-bgp.

seconds—When the on-startup keyword is configured, causes the 
overload bit to be set upon system startup and remain set for this 
number of seconds. The range is from 5 to 86400 seconds. 

wait-for-bgp—When the on-startup keyword is configured, causes 
the overload bit to be set upon system startup and remain set until BGP 
has converged. If BGP does not signal IS-IS that it is converged, IS-IS 
will turn off the overload bit after 10 minutes.

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).

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.

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.

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.
