Refresh Interval (MAX) The RSVP value, R, which is used to set the average 
interval between Path and Resv refresh messages, 
specified in milliseconds. 
Note that values for the refresh_interval and 
refresh_multiple should be configured such that the 
following inequality is obeyed:
6 * refresh_interval * (refresh_multiple + 0.5) < 
0x7FFFFFFF.
Otherwise the time-to-die for the path value will be set 
to its maximum value and it is probable that the LSP 
will time out before a refresh arrives. 
If the value is decreased, then the new value takes effect 
the next time a refresh timer pops. If the value is 
increased, then the refresh time is increased gradually 
each time a refresh timer pops. The change will affect 
both new and existing LSPs.
The default is 30000.
Hello Enable Indicates whether the RSVP Hello mechanism is 
enabled on this LPort. The Hello mechanism is used for 
node level connectivity verification. This field is 
disabled by default
Hello Failure Interval 
(MAX)
The default period in msecs between sending Hello 
messages to all neighbors on this interface. If this field 
is set to zero (0), no Hello messages are sent by this 
interface. The value of the field may be changed at any 
time. Such a change will take effect the next time the 
hello timer pops. The default is 5000 msecs.
Hello Failure Limit 
(0-65535)
Number of Hello periods which may pass without 
receiving a successful Hello message from a partner 
before the Hello session times out. The value of this 
field may be changed at any time. The new value is used 
for subsequent checking of the Hello state. The default 
is three.
