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.

This command is not supported in loopback interface view.
