VLAN interface view
Parameter
level-1: Configure Level-1, instead of Level-2, adjacency on the current interface
only.
level-1-2: Configure both Level-1 and Level-2 adjacency on the current
interface.
level-2: Configure Level-2 adjacency on the current interface only.
Description
Use the isis circuit-level command to configure the neighboring circuit type.
Use the undo isis circuit-level command to restore the default setting.
By default, the value is level-1-2.
If the local router is a level-1-2 router and it is required to establish a correlation
with the peer router on a certain level (level-1 or level-2), this command can
specify the interface to send and receive hello packets of this level. Certainly, only
one type of hello packet is sent and received on the point-to-point link. In this way,
excessive processing is avoided, and the bandwidth is saved.
Related commands: is-level.
Example
When interface Vlan-interface 1 is connected with a non-backbone router in the
same area, you can set this interface as level-1, prohibiting the sending and
receiving of level-2 hello packets.
