Specifying the interval for sending IS-IS CSNP packets
On a broadcast network, perform this task on the DIS that uses CSNP packets to synchronize
LSDBs.
To specify the interval for sending IS-IS CSNP packets:
Step
Command
Remarks
1.
Enter system view.
system-view
N/A
2.
Enter interface view.
interface
interface-type
interface-number
N/A
3.
Specify the interval for
sending CSNP packets on
the DIS of a broadcast
network.
isis timer csnp seconds
[
level-1
| level-2
]
The default setting is 10 seconds.
Configuring a DIS priority for an interface
On a broadcast network, IS-IS must elect a router as the DIS at a routing level. You can specify a DIS
priority at a level for an interface. The greater the interface's priority, 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.
To configure a DIS priority for an interface:
Step
Command
Remarks
1.
Enter system view.

N/A
2.
Enter interface view.
interface

3.
Configure a DIS priority for
the interface.
isis dis-priority priority
[
level-1
|
level-2
]
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
Command

1.
Enter system view.

Disable the interface from
sending and receiving IS-IS
packets.
isis silent
By default, the interface can send
and receive IS-IS packets.
