Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive configuration information corresponding to a lower layer triggered mobility (LTM) operation associated with an LTM configured cell set, the configuration information indicating a group of candidate cells, of the LTM configured cell set, corresponding to a set of LTM-based radio link failure (RLF) conditions for declaring an RLF associated with a source cell. The UE may perform an RLF operation based on the set of LTM-based RLF conditions. Numerous other aspects are described.
