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.

3. Disable the interface from
sending and receiving IS-IS
packets.
isis silent
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.

isis small-hello
By default, the interface can send
standard hello packets.
