seconds
: Specifies the Hello interval, ranging from 3 to 255 and measured in seconds.
The default value is 10 seconds.
level-1
: Specifies the Level-1 Hello interval.
level-2
: Specifies the Level-2 Hello interval.
If no level is not specified, the Hello interval is set to Level-1-2, that is, both Level-1 and
Level-2 take effect.
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.
