Disabling An Interface From Sending/Receiving Is-Is Packets; Enabling An Interface To Send Small Hello Packets; Configuring Lsp Parameters - HP 6125XLG Configuration Manual

Step
1. Enter system view.
2. Enter interface view.
3. Configure a DIS priority for
the interface.

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.

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.
