To specify the IS-IS hello multiplier:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter interface view.

N/A
3. Specify the number of hello packets a
neighbor must miss before declaring
the router is down.

[ level-1 | level-2 ] Optional.
3 by default.
NOTE:
On a broadcast link, Level-1 and Level-2 hello packets are advertised separately; therefore, you need to
set a hello multiplier for each level. On a P2P link, Level-1 and Level-2 hello packets are advertised in P2P
hello packets, and you do not need to specify Level-1 or Level-2.
Configuring a DIS priority for an interface
On an IS-IS broadcast network, a router should be elected as the DIS at a routing level. You can specify
a DIS priority at a level for an interface. The greater the interfaces priority is, the more likely it becomes
the DIS. If multiple routers in the broadcast network have the same highest DIS priority, the router with the
highest MAC address becomes the DIS.

1. Enter system view. system-view N/A
2. Enter interface view.

Optional.
64 by default.
Disabling an interface from sending/receiving IS-IS packets
After 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 other routers know networks directly connected to the
interface.
