Before the configuration, accomplish the following tasks:
z
Configure the link layer protocol.
z
Configure an IP address for each interface, and make sure all neighboring nodes are reachable to
each other at the network layer.

Configuring the IS Level and Circuit Level
If only one area is available, it is recommended that:
z
Configure the IS level of all routers as Level-1 or Level-2 and don’t configure different levels in this
case because there is no need for all routers to maintain two identical LSDBs;
z
Configure the IS level as Level-2 on all routers in an IP network for scalability.
For an interface of a Level-1 (or Level-2) router, the circuit level can only be Level-1 (or Level-2). For an
interface of a Level-1-2 router, the default circuit level is Level-1-2; if the router only needs to form
Level-1 (or Level-2) neighbor relationships, you can configure the circuit level for its interfaces as
Level-1 (or Level-2) to limit neighbor relationship establishment.
Follow these steps to configure the IS level and circuit level:
