H3C S7500E Series Ethernet Switches
level-1-2: Configures the router to work on Level-1-2, which means it calculates routes
and maintains the LSDBs for both L1 and L2.
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 configure IS-IS router type.
Use the undo is-level command to restore the default.
The default router type is level-1-2.
It is recommended to configure system level when you configure IS-IS.
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. In this case, you are recommended to configure all the routers as Level-2 in the IP
network for scalability consideration.
