Use the debug mpls traffic-eng path ecmp command to display the ECMP-related debug information, such
as for BWV comparison when all other tiebreakers failed to yield a selected path. Use this command in
conjunction with the debug mpls traffic-eng path spf or debug mpls traffic-eng path lookup commands.
Restore Path Option
The restore path option signals a restore LSP after the double failure of both, primary and protect LSPs. The
restore LSP is signaled only after both, primary and protect LSPs fail or are administratively down and it is
destroyed when the primary LSP comes back up. If the sticky option is configured, and both, primary and
protect LSPs fail, restore LSP is destroyed when either the primary or protect LSP comes up. Also, restore
LSP can be SRLG capable if it is configured.
