level-1
: Configures the router to operate at Level-1, only calculate the intra-area routes
and maintain the LSDB of L1.
level-1-2
: Configures the router to operate at Level-2, calculate both the L1 and L2
routes and maintain the LSDB of L1 and L2.
level-2
: Configures the router to operate at Level-2, only switch L2 LSP and calculate
the L2 routes and maintain the LSDB of L2.
Description
Use the
is-level
command to configure the level of the IS-IS router.
Use the
undo is-level
command to restore the default value.
By default, the value is
level-1-2
.
We recommend setting the system Level, when you configure IS-IS.
If there is only one area, you are recommended to set the level of all the routers as
Level-1 or Level-2, because it is not necessary for all the routers to maintain two
identical databases. You are recommended to set all the routers to Level-2 for
convenient future extension, when applying them to IP network.
