cspf-group-computation

Use the cspf-group-computation mode when setting up a fate-sharing group.

Syntax

cspf-group-computation [ add-penalty | ignore-overload-bit | metric-type [ use-igp-metric | use-te-metric ] | use-bypass-metric ]

no cspf-group-computation

Command Default

The CSPF group computation mode is disabled, by default.

Parameters

add-penalty

Adds penalty of all matching cspf-groups to TE metric of the TE link.

ignore-overload-bit

Ignores the overload bit during CSPF computaton.

metric-type

Selects the metric type for CSPF computation.

use-igp-metric: Uses the IGP metric of the link for CSPF computation.

use-te-metric: Uses the TE metric of the link for CSPF computation.

use-bypass-metric: Uses the bypass LSPs path cost for the selection between bypass LSPs

Modes

MPLS policy configuration mode (config-router-mpls-policy).

Usage Guidelines

The no form of the command disables the CSPF group computation mode.

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

Examples

The following example specifies the CSPF-group computation for a fate-sharing group, and enables the add-penalty option.

device# configure
device(config)# router mpls
device(config-router-mpls)# policy
device(config-router-mpls-policy)# cspf-group-computation add-penalty

The following example enables the liberal mode of the bypass LSP selection.

device# configure
device(config)# router mpls
device(config-router-mpls)# policy
device(config-router-mpls-policy)# cspf-group-computation use-bypass-liberal
