Purpose
(Optional) Force a default route into the IS-IS routing domain.If you enter
route-map map-name, the routing process generates the default route if the
route map is satisfied.
(Optional) Configure the router to ignore LSPs with internal checksum
errors, instead of purging the LSPs. This command is enabled by default
(corrupted LSPs are dropped). To purge the corrupted LSPs, enter the no
ignore-lsp-errors router configuration command.
(Optional Configure the area authentication password, which is inserted in
Level 1 (station router level) LSPs.
(Optional) Configure the routing domain authentication password, which is
inserted in Level 2 (area router level) LSPs.
(Optional) Create a summary of addresses for a given level.
(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.
(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).
(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.
(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.
