Setter method for propagate, mapped from YANG variable /network_instances/network_instance/protocols/protocol/ospfv2/areas/area/lsdb/lsa_types/lsa_type/lsas/lsa/nssa_external_lsa/state/propagate (boolean)
    If this variable is read-only (config: false) in the
    source YANG file, then _set_propagate is considered as a private
    method. Backends looking to populate this variable should
    do so via calling thisObj._set_propagate() directly.

    YANG Description: When this bit is set to true, an NSSA border router will
translate a Type 7 LSA (NSSA External) to a Type 5 LSA
(AS External).
