Summary (Is-Is View) - HP FlexNetwork 3600 v2 Series Command Reference Manual

Parameters
on-startup: Sets the overload bit upon system startup.
start-from-nbr system-id [ timeout1 [ nbr-timeout ] ]: Starts the nbr-timeout timer when the router
begins to establish the neighbor relationship with the neighbor after system startup. If the neighbor
relationship is formed within the nbr-timeout interval, IS-IS keeps the overload bit set; if not, the bit is
cleared. IS-IS keeps the overload bit set within the timeout1 interval after the neighbor relationship is
formed within the nbr-timeout interval.
•
system-id: Specifies the neighbor.
•
timeout1: The timeout1 interval is in the range of 5 to 86400 seconds and defaults to 600
seconds.
•
nbr-timeout: The timer has an interval from 5 to 86400 seconds. The default is 1200 seconds.
timeout2: Sets the overload bit within the timeout2 interval after system startup. The interval is in the
range of 5 to 86400 seconds and defaults to 600 seconds.
allow: Allows advertising address prefixes. By default, no address prefixes are allowed to be
advertised when the overload bit is set.
external: Allows advertising IP address prefixes redistributed from other routing protocols with the
allow keyword specified.
interlevel: Allows advertising IP address prefixes learned from different IS-IS levels with the allow
keyword specified.
Description
Use set-overload to set the overload bit.
Use undo set-overload to clear the overload bit.
The overload bit is not set by default.
If the on-startup keyword is not specified, the command sets the overload bit immediately until the
undo set-overload command is executed.
If the on-startup keyword is specified, IS-IS sets the overload bit upon system startup and keeps it
set within the timeout2 interval.
Examples
# Set overload flag on the current router.
<Sysname> system-view
[Sysname] isis 1
[Sysname-isis-1] set-overload
