RSVP Commands
Page 296 7450 ESS MPLS Guide
rapid-retransmit-time
Syntax rapid-retransmit-time hundred-milliseconds
no rapid-retransmit-time
Context config>router>rsvp
Description This command defines the value of the Rapid Retransmission Interval. It is used in the re-
transmission mechanism to handle unacknowledged message_id objects and is based on an
exponential back-off timer.
Re-transmission interval of a RSVP message with the same message_id = 2 * rapid-retransmit-time
interval of time.
The node stops re-transmission of unacknowledged RSVP messages:
• If the updated back-off interval exceeds the value of the regular refresh interval.
• If the number of re-transmissions reaches the value of the rapid-retry-limit parameter, which-
ever comes first.
The Rapid Retransmission Interval must be smaller than the regular refresh interval configured in
config>router>rsvp>refresh-time.
The no form of this command reverts to the default value.
Default 5
Parameters hundred-milliseconds — Specifies the rapid retransmission interval.
Values 1 – 100, in units of 100 msec.
rapid-retry-limit
Syntax rapid-retry-limit number
no rapid-retry-limit
Context config>router>rsvp
Description This command is used to define the value of the Rapid Retry Limit. This is used in the retransmission
mechanism based on an exponential backoff timer in order to handle unacknowledged message_id
objects. The RSVP message with the same message_id is retransmitted every 2 * rapid-retransmit-
time interval of time. The node will stop retransmission of unacknowledged RSVP messages
whenever the updated backoff interval exceeds the value of the regular refresh interval or the number
of retransmissions reaches the value of the rapid-retry-limit parameter, whichever comes first.
The no form of this command reverts to the default value.
Default 3
Parameters number — Specifies the value of the Rapid Retry Limit.
Values 1 – 6, integer values
