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:
Ste
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:

N/A
3. Configure a DIS priority for
the interface.
isis dis-priority value [ 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.
