Version Description
9.9(0.0) Introduced on the FN IOM.
9.2(0.0) Introduced on the MXL 10/40GbE Switch IO Module.
Usage Information
Configure a network entity title (the net command) to specify the area address and the router system ID.
Enable routing on one or more interfaces to establish adjacencies and establish dynamic routing.
You can configure only one IS-IS routing process to perform Level 2 routing. A level-1-2 designation performs
Level 1 and Level 2 routing at the same time.
Related Commands
ip router isis — configures IS-IS routing processes for IP on interfaces and attaches an area designator to the
routing process.
net — configures an IS-IS network entity title (NET) for a routing process.
is-type — assigns a type for a given area.
set-overload-bit
To set the overload bit in its non-pseudonode LSPs, configure the router. This setting prevents other routers from using it as an
intermediate hop in their shortest path first (SPF) calculations.
Syntax
set-overload-bit
To return to the default values, use the no set-overload-bit command.
Defaults Not set.

9.9(0.0) Introduced on the FN IOM.
9.2(0.0) Introduced on the MXL 10/40GbE Switch IO Module.
Usage Information Set the overload bit when a router experiences problems, such as a memory shortage due to an incomplete link
state database which can result in an incomplete or inaccurate routing table. If you set the overload bit in its LSPs,
other routers ignore the unreliable router in their SPF calculations until the router has recovered.
