This command configures the circuit type level for one or all IS-IS VLANs.
|vlan all||Applies the selected circuit type to all IS-IS VLANs.|
|vlan_name||Specifies a single VLAN to which the circuit type configuration applies.|
|level [1 | 2 | both-1-and-2]||Sets the circuit type level to level 1, level 2, or to both level 1 and level 2.|
Hello PDUs are only sent on the specified level for the selected VLANs. This can be useful for level 1/level 2 routers that are neighbors.
Note that for per-level VLAN configurable parameters L1 and L1/L2, point-to-point interfaces use the level 1 parameters, and L2-only point-to-point interfaces use the L2 parameters.
The following command configures all IS-IS VLANs to use circuit type level 1:
configure isis vlan all circuit-type level 1
