This flag signals that on the next reestablishment attempt, an inactive circuit will try the network's OSPF-computed path rather than its originally defined path, helping the admin understand why a PVC pinned to a custom route might come back up on a different path than expected. For example, seeing this set to 1 on a circuit that just failed on its defined path explains why its next successful activation shows a cktPath different from the cktDefinedPath the admin originally configured.
