Configures the device to choose the path with the highest available bandwidth or the lowest available bandwidth.
The default is the tie-breaking random mode.
Causes CSPF to choose the path with the highest available bandwidth (that is, the path with the least utilized links).
Causes CSPF to choose the path with the lowest available bandwidth (that is, the path with the most utilized links).
MPLS LSP configuration mode (config-router-mpls-lsp-lsp_name )
MPLS router bypass LSP configuration mode (config-router-mpls-bypass-lsp-bypass_name )
MPLS router MPLS interface dynamic bypass configuration mode (config-router-mpls-if-ethernet-slot/port -dynamic-bypass)
The no form of the command removes the tie-breaking configuration and reverts to the default mode.
The user can configure an interface level tie-breaking option for the CSPF calculation of dynamic bypass LSPs to be created for the protected MPLS interface. The set value is used for dynamic bypass LSP path computation tie-breaking procedure.
MPLS is supported on the Extreme 8820, SLX 9740, SLX 9640, and SLX 9540 devices only.
In the following example, the configuration causes the CSPF to select the path with the highest available bandwidth when choosing among equal cost paths calculated for LSP tunnel1.
device# configure device(config)# router mpls device(config-router-mpls)# lsp tunnel1 device(config-router-mpls-lsp-tunnel1)# tie-breaking least-fill
The following example configures the tie-breaking path bandwidth to the least-fill option for dynamic bypass MPLS Ethernet interface 2/8 .
device# configure device(config)# router mpls device(config-router-mpls)# mpls-interface ethernet 2/8 device(config-router-mpls-if-ethernet-2/8)# dynamic-bypass device(config-router-mpls-if-ethernet-2/8-dynamic-bypass)# tie-breaking least-fill
