Refresh Reduction Commands
This chapter describes the RSVP-TE Refresh Reduction commands:
ack-send-timer
Use this command to configure the timer to send an acknowledgement message. Timer configuration increases the chances of piggy backing multiple acknowledgement messages but also adds delay in acknowledgment received by neighbor node. So, use this command with exact knowledge of optimum time.
Note: Configure this command with a value within the limit of ack-wait-timeout to avoid frequent timeout.
Command Syntax
ack-send-timer <1-5>
no ack-send-timer
Parameter
<1-5>
Value in seconds for acknowledgement send timer.
Default
By default, acknowledgement message is transmitted immediately without piggy-backing.
Command Mode
Router mode
Applicability
This command was introduced before OcNOS version 6.4.1.
Examples
#configure terminal
(config)#router rsvp
(config-router)# ack-send-timer 1
(config-router)# commit
(config-router)# no ack-send-timer
(config-router)# commit
ack-wait-timeout
Use this command to configure the acknowledgement wait timeout for all RSVP-TE neighbors.
Use the no parameter with this command to revert to the default acknowledgement wait timeout.
Command Syntax
ack-wait-timeout <1-65535>
no ack-wait-timeout
Parameter
<1-65535>
Specify a value for the acknowledgement wait timeout in seconds. The default timeout value is 10 seconds.
Default
By default, ack wait timeout is 10 seconds
Command Mode
Router mode
Applicability
This command was introduced before OcNOS version 1.3.
Examples
#configure terminal
(config)#router rsvp
(config-router)#ack-wait-timeout 5
(config)#router rsvp
(config-router)#no ack-wait-timeout
message-ack
Use this command to enable message acknowledgment for all messages being sent to neighbors that are known to support refresh reduction.
Use the no parameter with this command to disable message acknowledgment for all messages being sent to neighbors.
Command Syntax
message-ack
no message-ack
Parameters
None
Default
By default, Message Acknowledgment is disabled
Command Mode
Router mode
Applicability
This command was introduced before OcNOS version 1.3.
Examples
#configure terminal
(config)#router rsvp
(config-router)#message-ack
(config)#router rsvp
(config-router)#no message-ack
refresh-reduction
Use this command to enable refresh reduction capability advertisement for all interfaces.
Use the no parameter with this command disable refresh reduction capability advertisement for all interfaces.
Command Syntax
refresh-reduction
no refresh-reduction
Parameters
None
Default
By default, Refresh reduction mechanism is enabled
Command Mode
Router mode
Applicability
This command was introduced before OcNOS version 1.3.
Examples
#configure terminal
(config)#router rsvp
(config-router)#refresh-reduction
(config)#router rsvp
(config-router)#no refresh-reduction
rsvp ack-wait-timeout
Use this command to configure the acknowledgment wait timeout for all neighbors detected via the specific interface.
Use the no parameter with this command to revert to the default acknowledgment wait timeout for the specified interface.
Command Syntax
rsvp ack-wait-timeout <1-65535>
no rsvp ack-wait-timeout
Parameters
<1-65535>
Specify a value for the acknowledgment wait timeout in seconds. The default timeout value is 10 seconds.
Default
By default, rsvp ack wait timeout is 10 seconds
Command Mode
Interface mode
Applicability
This command was introduced before OcNOS version 1.3.
Examples
#configure terminal
(config)#interface eth0
(config-if)#rsvp ack-wait-timeout 5
(config)#interface eth0
(config-if)#no rsvp ack-wait-timeout
rsvp message-ack
Use this command to enable message acknowledgment for all messages being sent to the neighbors that have been detected via the specific interface.
Use the no parameter with this command to disable message acknowledgment for all messages being sent to the neighbors that have been detected via the specified interface.
Command Syntax
rsvp message-ack
no rsvp message-ack
Parameters
