interface

election on the interface
By default, the interface priority is 64. If the level is not specified, it defaults to setting
both the Level-1 and level-2 priority.
5.2.12 Setting Interface Circuit Level
Perform the following configurations in Interface view.
Table 5-12 Setting interface circuit level
Set interface circuit level
Restore the default interface circuit level
Note:
Only when the router to which the interface belongs is of Level-1-2 type, is the
modification to the interface circuit level meaningful, otherwise, the type of the router
determines the level of adjacency relation.
You can set the circuit level to limit what adjacency can be established for the interface.
For example, Level-1 interface can only have Level-1 adjacency. Level-2 interface can
only have Level-2 adjacency. For the Level-1-2 router, you can configure some
interfaces to Level-2 to prevent transmitting Level-1 Hello packets to Level-2 backbone
so as to save the bandwidth. However Level-1 and Level-2 use the same kind of Hello
packet over the p2p link, and therefore such setting is unnecessary in this case.
By default, the circuit-level on the interface route is level-1-2.
