Adaptive Fast Reroute (FRR) and Global Revertiveness

Setting the revertive hold time
Use the revertive hold-time command to specify the time the LSP holds before attempting a new
path on the FRR LSP.
Brocade(config-mpls)# lsp t1
Brocade(config-mpls-lsp-t1)# adaptive
Brocade(config-mpls-lsp-t1)# frr
Brocade(config-mpls-lsp-t1-frr)# revertive mode global
Brocade(config-mpls-lsp-t1-frr)# revertive holdtime 20
Syntax: [no] revertive hold-time hold-time-value
The hold-time-value parameter specifies the hold time value in seconds. The hold-time is the time
between the primary LSP failure and the trigger of new instance of LSP by global revertiveness.
Possible range is one through 60 seconds.
The default is five seconds.
The [no] option sets it the timer to the default.
Global Revertiveness configurations
Global revertiveness is enabled by default in FRR mode for an adaptive LSP.
