Description
Use the isis timer hello command to configure the interval of sending Hello 
packet of the corresponding level.
Use the undo isis timer hello command to restore the default value.
On a broadcast link, level-1 and level-2 Hello packets will be sent respectively and 
their intervals should also be set respectively. Such settings are unnecessary on 
point-to-point links. The shorter the sending interval is, the more system resources 
are occupied to send Hello packets. Therefore, the interval should not be too short 
and should be set according to actual conditions.
Related command: isis timer holding-multiplier.
Example
# Set the Hello packet of Level-2 to be transmitted every 20 seconds on Interface 
Vlan-interface 10.

Parameter
minimal: Sets the sending interval to the minimum value. In this case, the hold 
time is 1 second.
level-1: Specifies that the sending interval resulting from this command is for 
level-1 Hello packets.
level-2: Specifies that the sending interval resulting from this command is for 
level-2 Hello packets.
If neither level-1 nor level-2 is specified, the sending interval is set for both 
Level-1 and Level-2 Hello packets by default, that is, this command takes effect on 
both Level-1 and Level-2 Hello packets.
Description
Use the isis timer hello minimal command to configure the IS-IS system to send 
the Hello packets at the corresponding level(s) in Fast Hello Mode. If the number 
of consecutively sent Hello packets is not specified, the system sends three Hello 
packets per second.
Use the undo isis timer hello minimal command to restore the default setting, 
that is, 10 seconds.
