The Solicitation PDU RPL Configuration Client model behavior can be configured with the transmission timeout option :kconfig:option:`CONFIG_BT_MESH_SOL_PDU_RPL_CLI_TIMEOUT`.
The :kconfig:option:`CONFIG_BT_MESH_SOL_PDU_RPL_CLI_TIMEOUT` controls how long the Solicitation PDU RPL Configuration Client waits
for a response message to arrive in milliseconds. This value can be changed at runtime using :c:func:`bt_mesh_sol_pdu_rpl_cli_timeout_set`.
