You must enable routing on one or more interfaces to establish adjacencies and establish dynamic routing. Only one IS-IS routing process can be configured 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 net is-type Configure IS-IS routing processes for IP on interfaces and attach an area designator to the routing process. Configure an IS-IS network entity title (NET) for a routing process. Assign a type for a given area. set-overload-bit e Configure the router to set the overload bit in its non-pseudonode LSPs. This 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, enter no set-overload-bit. Defaults Not set. Command Mode ROUTER ISIS (for IPv4) CONFIGURATION-ROUTER-ISIS-ADDRESS-FAMILY-IPV6 (for IPv6) 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.
