HP MSR2000/3000/4000 Router Series MPLS Command Reference

127
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 RSVP GR is disabled
but FRR is enabled on the local device, it performs an FRR.
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

Parameters
number: Specifies the PSB and RSB timeout multiplier in the range of 3 to 255.
Usage guidelines
The PSB and RSB timeout is computed in this formula: Timeout = (keep-multiplier+0.5) × 1.5 × refresh-time.
Refresh-time is the interval at which the peer device advertises the Path and Resv messages to the local
device.
To prevent too many PSBs and RSBs from occupying system resources, the device removes a PSB or RSB
if no Path or Resv message is received within the timeout interval.
