RSVP refresh reduction
1
RSVP bundle messages are disabled by default for all interfaces. To enable bundle messages on
an interface, use commands such as the following.
Brocade(config)# router mpls
Brocade(config-mpls)# mpls-interface eth 3/13
Brocade(config-mpls-if-e1000-3/13)# rsvp-refresh-reduction bundle-message
bundle-send-delay 20
The previous commands enable RSVP bundle messages on interface 3/13 with a
bundle-send-delay of 20 milliseconds.
Syntax: [no] rsvp-refresh-reduction bundle-message [bundle-send-delay milliseconds]
The bundle-send-delay option specifies the maximum period (in milliseconds) that an outgoing
message can be delayed in order to create a multi-message bundle before sending. This delay is
retained for the interface even when bundle messages are disabled.
When the RSVP neighbor does not support refresh reduction, the interface does not bundle
messages even when bundle messages are locally enabled. Use the [no ] version of the command
to disable RSVP bundle messages on this interface.
NOTE
Summary refresh is a more effective tool for RSVP refresh message overhead reduction.
Configuring RSVP summary refresh
RFC 2961 extends RSVP to create IDs for RSVP messages. When RSVP summary refresh is enabled
on an interface, the device suppresses the sending of unchanged Path and Resv messages
(refresh messages) and instead sends a summary message listing the IDs of Path and Resv
messages that are to be refreshed. Summary refresh does not affect the sending of RSVP trigger
messages that signal changes of state.
RSVP summary refresh is disabled by default for all interfaces. To enable summary refresh on an
interface, use commands such as the following.
Brocade(config)# router mpls
Brocade(config-mpls)# mpls-interface eth 3/13
Brocade(config-mpls-if-e1000-3/13)# rsvp-refresh-reduction summary-refresh
The previous commands enable the sending of RSVP summary refresh messages on interface
3/13.
Syntax: [no] rsvp-refresh-reduction summary-refresh
When the RSVP neighbor does not support refresh reduction, the interface does not send summary
refresh messages, even though the feature is locally enabled. It instead continues to resend full
Path and Resv refresh messages. Use the [no] version of the command to manually disable
summary refresh on this interface.
