reliable-messaging

When RSVP reliable messaging is enabled on an interface of the SLX-OSdevice, RSVP trigger messages sent out on that interface includes a message ID and a request for acknowledgment from the RSVP neighbor.

Syntax

reliable-messaging [ rapid-retrans-decay percent ] | [ rapid-retrans-interval milliseconds ] | [ rapid-retry-limit number ]

no reliable-messaging [ rapid-retrans-decay percent ] | [ rapid-retrans-interval milliseconds ] | [ rapid-retry-limit number ]

Command Default

The command is disabled, by default.

Parameters

rapid-retrans-decay percent: Specifies the percentage increase in the rapid transmission interval for each consecutive unacknowledged RSVP message. The range is from 0 - 100, with a default of 100.
rapid-retrans-interval milliseconds: Specifies the interval, in milliseconds, for an unacknowledged message to be resent. The range is from 100-30000 milliseconds, with a default of 2000 milliseconds.
rapid-retry-limit number: Specifies the maximum number of retries for an unacknowledged message. The range is 1-16, with a default value of 5.

Modes

MPLS interface RSVP mode (config-router-mpls-eth-x/x).

MPLS RSVP mode (config-router-mpls-rsvp).

Usage Guidelines

When acknowledgment is not received, the trigger message is re-transmitted using the retransmission parameters configured on the interface.

The no form of the command removes reliable messaging.

MPLS is supported only on devices based on the DNX chipset family. For a list of such devices, see "Supported Hardware".

Examples

The following example enables RSVP reliable messaging on MPLS interface 0/13 .

device# configure
device(config)# router mpls
device(config-router-mpls)# mpls-interface ethernet 0/13
device(config-router-mpls-eth-0/13)# rsvp
device(config-router-mpls-eth-0/13-rsvp)# reliable-messaging

The following example configures the rapid-retrans-decay option to 1 percent, the rapid-retrans-interval option to 100 milliseconds, and the rapid-retry-limit option to 1 try.

device# configure
device(config)# router-mpls
device(config-router-mpls)# rsvp
device(config-router-mpls-rsvp)#  reliable-messaging rapid-retrans-decay 1 rapid-retrans-interval 100 rapid-retry-limit 1
