Parameters
level-1
: Specifies Level-1, which means IS-IS only calculates intra-area routes and maintains the Level-1
LSDB.
level-1-2
: Specifies Level-1-2, which means IS-IS calculates routes and maintains the LSDBs for both Level-1
and Level-2.
level-2
: Specifies Level-2, which means IS-IS calculates routes and maintains the LSDB for Level-2 only.
Usage guidelines
If only one area exists, configure all the routers as either Level-1 or Level-2, because the routers do not
need to maintain two identical LSDBs at the same time.
If the only area is an IP network, configure all the routers as Level-2 for scalability.
