Step 1. Enter system view. 2. Enter interface view. 3. Configure a DIS priority for the interface. Command system-view interface interface-type interface-number isis dis-priority value [ level-1 | level-2 ] Remarks N/A N/A The default setting is 64. Disabling an interface from sending/receiving IS-IS packets After being disabled from sending and receiving hello packets, an interface cannot form any neighbor relationship, but can advertise directly connected networks in LSPs through other interfaces. This can save bandwidth and CPU resources, and ensures that other routers know networks directly connected to the interface. To disable an interface from sending and receiving IS-IS packets: Step 1. Enter system view. 2. Enter interface view. 3. Disable the interface from sending and receiving IS-IS packets. Command system-view interface interface-type interface-number isis silent Remarks N/A N/A By default, the interface can send and receive IS-IS packets. Enabling an interface to send small hello packets IS-IS messages cannot be fragmented at the IP layer because they are directly encapsulated in frames. Any two IS-IS neighboring routers must negotiate a common MTU. To avoid sending big hellos to save bandwidth, enable the interface to send small hello packets without CLVs. To enable an interface to send small hello packets: Step 1. Enter system view. 2. Enter interface view. 3. Enable the interface to send small hello packets without CLVs. Command system-view interface interface-type interface-number isis small-hello Remarks N/A N/A By default, the interface can send standard hello packets.
