3Com S7906E Command Reference Manual page 848

level-2: Configures the router to work on Level-2, which means it calculates routes and maintains the
LSDB for L2 only.
Description
Use the is-level command to specify the IS level.
Use the undo is-level command to restore the default.
The default IS level is level-1-2.
You can configure all the routers as either Level-1 or Level-2 if there is only one area, because there is
no need for all routers to maintain two identical databases at the same time. If the only area is an IP
network, you are recommended to configure all the routers as Level-2 for scalability.
