Description
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.
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
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.
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.
