By default, this is not configured.
Command Mode
Router Configuration Mode.
Command Default Level
Level: 12.
Usage Guideline
This command is used to force the IS-IS process to set the overload-bit in its non-pseudo node LSPs.
Normally, the setting of the overload bit is allowed only when a router runs into problems. For example,
when a router is experiencing a memory shortage, it might be that the LSPDB isn't complete, resulting in
an incomplete or inaccurate routing table. By setting the overload bit in its LSPs, other router can ignore
the unreliable router in their SPF calculations until the router has recovered from its problems.
Unless the on-startup keyword is specified, this command sets the overload bit immediately.
In addition to setting the overload bit, it might be a good idea to suppress certain types of IP prefix
advertisements from LSPs. For example, allowing IP prefix propagation between level 1 and level 2
effectively makes a node a transit node for IP traffic, which might be undesirable. The suppress keyword
used with the interlevel or external keyword (or both) accomplishes that suppression while the overload
bit is set.
Example
This example shows how to configure the overload bit upon startup and suppresses redistribution
between IS-IS levels and suppresses redistribution from external routing protocols while the overload bit
is set.
Switch# configure terminal
Switch(config)# router isis
Switch(config-router)# net 49.0001.0001.0001.0001.00
Switch(config-router)# set-overload-bit on-startup 100 suppress interlevel external
Switch(config-router)#

Default
None.
Command Mode
EXEC Mode or Any Configuration Mode.
Command Default Level
Level: 1.
Usage Guideline
This command is used to display the IS-IS IP routing table.
