Configuring IS-IS Global Parameters
Purpose
(Optional Configures the area authentication password, which
is inserted in Level 1 (station router level) LSPs.
(Optional) Configures the routing domain authentication
password, which is inserted in Level 2 (area router level)
LSPs.
(Optional) Creates a summary of addresses for a given level.
(Optional) Sets 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) Sets 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).
