revertive global

The revertive mode global command can be executed only on LSPs with FRR and adaptive enabled.

Syntax

revertive global [ disable | enable ]
no revertive mode global

Command Default

Global revertiveness is enabled by default for LSPs with FRR and adaptive enabled.

Parameters

disable
Disables global revertiveness.
enable
Enables global revertiveness.

Modes

MPLS LSP Fast Reroute.

Usage Guidelines

The no option disables global revertiveness on an LSP.

When adaptive is disabled, then global revertiveness is also disabled.

MPLS is supported on the Extreme 8820, SLX 9740, SLX 9640, and SLX 9540 devices only.

Examples

The following example enables global revertiveness on LSP t1.

device# config
device(config)# router mpls
device(config-router-mpls)# lsp t1
device(config-router-mpls-lsp-t1)# adaptive
device(config-router-mpls-lsp-t1)# frr
device(config-router-mpls-lsp-t1-frr)# revertive global enable

The following example is of an adaptive LSP.

device# configure terminal 
device(config)# router mpls 
device(config-mpls)# lsp t1
device(config-router-mpls-lsp-t1)# to 10.3.3.3
device(config-router-mpls-lsp-t1)# from 10.2.2.2
device(config-router-mpls-lsp-t1)# traffic-eng mean-rate 1000
device(config-router-mpls-lsp-t1)# adaptive
device(config-router-mpls-lsp-t1)# frr
device(config-router-mpls-lsp-t1-frr)# facility-backup 
device(config-router-mpls-lsp-t1-frr)# exit 
device(config-router-mpls-lsp-t1)# enable 
device(config-router-mpls)#

The following example changes the FRR bandwidth for an adaptive LSP.

device(config)# 
device(config)# router mpls 
device(config-router-mpls)# lsp t1
device(config-router-mpls-lsp-t1)# frr
device(config-router-mpls-lsp-t1-frr)# bandwidth 1000
device(config-router-mpls-lsp-t1-frr)# exit 
device(config-router-mpls-lsp-t1)# commit 

The following example show how global revertiveness is enabled by default in FRR mode for an adaptive LSP.

device# configure 
device(config)# router mpls 
device(config-router-mpls)# policy
device(config-router-mpls-policy)# retry-limit 20
device(config-router-mpls-policy)# exit
device(config-router-mpls)# lsp t1
device(config-router-mpls-lsp-t1)# adaptive
device(config-router-mpls-lsp-t1)# frr
device(config-router-mpls-lsp-t1-frr)# revertive mode global
device(config-router-mpls-lsp-t1-frr)# revertive holdtime 20
device(config-router-mpls-lsp-t1-frr)# exit 
device(config-router-mpls-lsp-t1)# commit 
device(config-router-mpls-lsp-t1)#
