2: System level 

seconds: Specifies the interval in seconds for sending hello packets, ranging from 3 to 255.  

level-1: Specifies the interval for sending Level-1 hello packets.  

level-2: Specifies the interval for sending Level-2 hello packets.  

Use the isis timer hello command to specify the interval for sending hello packets. 

Use the undo isis timer hello command to restore the default.  

The default hello interval is 10 seconds. 

 

z 

Level-1 and Level-2 hello packets are sent independently on a broadcast network, so you need to 

specify an interval for the two levels respectively. On a P2P link, Level-1 and Level-2 packets are 

both sent in P2P hello packets, and you need not specify an interval for two levels respectively. 

z 

As the shorter the interval is, the more system resources will be occupied, you should configure a 

proper interval as needed. 

z 

If no level is specified, the hello interval applies to both Level-1 and Level-2.
