Parameters
times: Specifies the maximum number of consecutive lost or erroneous hellos, in the range of 3 to 10.
Usage guidelines
When the number of consecutive lost hellos or erroneous hellos received from a neighbor reaches the
maximum value specified by this command, the device regards the neighbor failed. If RSVP GR is
enabled, the local device acts as a GR helper to help the neighbor to perform GR.
If the maximum number is too big, neighbor failures cannot be promptly detected. If the maximum
number is too small, an operating neighbor might be regarded failed.
This command can take effect only after the RSVP hello extension function has been enabled by using the
rsvp hello enable command.
Examples
# Set the maximum number of consecutive lost or erroneous hellos to 6.
<Sysname> system-view
[Sysname] rsvp
[Sysname-rsvp] hello lost 6
