To display CSPF fate-sharing group configuration for all groups configured on a device, use the show mpls configuration command or the show run command.
To display CSPF fate-sharing group information for a specific CSPF group, use the show running-config router mpls cspf-group cspf-group name command. The output from the show running-config router mpls command. In the following example output, the CSPF fate-sharing group information is displayed for CSPF group gold.
device# show running-config router mpls cspf-group gold cspf-group gold penalty 65535 node 10.7.7.3 node 10.7.7.8
Fate-sharing group membership for any given TE link or node consists of its own membership to the group, and the TE node to which it belongs. The output from the show mpls te database detail command is enhanced to display the fate-sharing groups to which the TE links or nodes belong. In the following example output, node 10.20.20.20 displays fate-sharing group information for group1/100 and group2/10.

The show running-config router mpls lsp lsp_name command displays detailed information about a specific LSP name. The output from the show running-config router mpls lsp lsp_name command is enhanced to display whether the fate-sharing group information is applied to the path computation for a specified LSP. When the fate-sharing group information is applied, "yes" is displayed in the field. When fate-sharing group information is not applied, "no" is displayed in the field. Fate-sharing group information can also be applied to the path computation for a secondary LSP or a bypass LSP path. In the following example, the fate-sharing group information is applied to LSP test2.

In the following example output, the primary LSP path, and the secondary bypass LSP path is UP. The add-penalty parameter is enabled under the CSPF group computation mode as highlighted below.
