[Sysname] interface gigabitethernet 2/1/1
[Sysname-Gigabitethernet2/1/1] isis enable
[Sysname-Gigabitethernet2/1/1] isis bfd enable
isis circuit-level
Use isis circuit-level to set the circuit level for the interface.
Use undo isis circuit-level to restore the default.
Syntax
isis circuit-level [ level-1 | level-1-2 | level-2 ]
undo isis circuit-level
Default
An interface can establish either the Level-1 or Level-2 adjacency.
Views
Interface view
Default command level
2: System level
Parameters
level-1: Sets the circuit level to Level-1.
level-1-2: Sets the circuit level to Level-1-2.
level-2: Sets the circuit level to Level-2.
Usage guidelines
For a Level-1 (Level-2) router, the circuit level can only be Level-1 (Level-2). For a Level-1-2 router, you need
to specify a circuit level for a specific interface to form only the specified level neighbor relationship.
Examples
# GigabitEthernet 4/0/1 is connected to a non-backbone router in the same area. Configure the circuit
level of serial 2/0 as Level-1 to prevent sending and receiving Level-2 Hello packets.
